Oasys LS DYNA Environment Software Section 2 Oasys PRIMER Reading amp Writing Files The reasons for this have not been explained adequately however in an attempt to improve network performance some i o tuning parameters have been added under the Options button on the Model Read panel These allow the user to change the buffer size used for disk i o and also the frequency with which progress is echoed to the screen and the user interface is polled and updated during i o The user in question reported some improvement when the buffer size was increased from its default typically 4 KBytes to 64 kBytes and it is possible that other users experiencing slow network i o performance may be able to improve performance by changing these parameters e Case 11536 Keyword input read has acquired an OPTIONS panel in which the following may be set 1 Read only a single definition following a keyword header only applicable to AIRBAG EOS HOURGLASS and MAT This is to handle the cases where an older version of PRIMER is used to read a newer format input file in which extra lines have been added to card formats Such definitions fail even when written out one per header since the excess lines are treated as the start of new definitions By reading only one definition per header and skipping any excess lines such decks can be read 2 Normally severe errors encountered on keyword read are handled by terminate r

8. If nodes were labelled dynamically using quick pick either by picking or by typing in their labels they would be displayed but then the labels would disappear if the view was changed This has now been corrected dynamic labels on nodes remain persistent as with labels on other entity types until cleared deliberately or the image is explicitly redrawn e Case 10601 When performing WRITE or XY_PLOT operations on cut section data the data component buttons would be mapped correctly when first used but thereafter only FX would appear A similar problem could also occur to some of the other more exotic component names in this context This has now been fixed e Case 10635 A crash could occur on some platforms when the plotting mode was switched to BEAM and the ATTRIBUTES sub option was used The actual effect or lack of it would be platform dependent This has now been fixed e Case 10670 If WRITE was used and the component selection panel within it also used then menu corruption or possibly a crash could occur if a second model was read in and a second cycle of WRITE select data component was performed This has now been fixed e Case 10697 The command line syntax for WRITE sometimes failed to select the items requested The symptoms were either that nothing was selected or that the most recent menu interface selection was used in error This has now been fixed Case 10710 Ove Arup amp Partners Ltd Pg 105 Oa
9. and would appear as errors in computing root assembly angles These have now been fixed e Case 11992 When MECHANISMs were added to release 9 3 they were integrated with the existing DUMMY capability and one enhancement was that once a DUMMY had been positioned the reference orientation of each of its assemblies would be written to any subsequent keyword output file However this failed to take into account any rotation of the dummy as a whole meaning that if a dummy was rotated prior to positioning its limbs the model was written out and then crucially read back into PRIMER for further positioning the angles of the root assembly reported in the dummy positioning menu would be wrong This wouldn t affect the actual dummy position or geometry only the reported angles This has now been corrected by testing prior to output whether the dummy as a whole has been rotated and if it has adding its current orientation as an optional 3 rows to the H POINT card of the DUMMY definition This change is backwards compatible with existing decks since if these extra 3 lines are absent then a unit matrix i e no whole body rotation of the dummy is assumed e Case 11909 If a DUMMY definition was put on the clipboard and then saved to another model then unless only nodes and elements were used a range of errors would be generated and the save operation would fail This was because a transient bare dummy definition without its assoc

Case 8979 In D3PLOT 9 2 the locate in tree quick pick options did not work when they were accessed via the right mouse button This has been fixed in version 9 3 e Case 9088 In D3PLOT 9 3 user defined titles are stored in the settings file if they have been defined If a windows title is the default one from the PTF file including swapped titles then it is not written to the settings file as it would automatically overwrite the title from a PTF file if the setting file was read into another D3PLOT session e Case 9301 When replaying Reporter template files the size of the graphics window in D3PLOT was ignored In cases where the user used the default size this wasn t an issue since the size on playback would match that when recorded however if the user had set a particular resolution it could be annoying Therefore when Reporter plays back template files the D3PLOT window size will now match exactly that used when the template file was recorded e Case 9310 In D3PLOT 9 2 the full pathname of models could not be seen in the Rescan Reread Close model panels if the filename was more than about 70 characters In version 9 3 the full pathname is displayed using hover text Ove Arup amp Partners Ltd Pg 102 Oasys Suite v9 3 30 August 2008 Release Notes Oasys LS DYNA Environment Software Section 3 Oasys D3PLOT Bugs fixed in version 9 3 e Case 9421 An error has been found in the reading of ASCII groups files asc If th

ID Option is turned on in the option panel e Case 11094 Internal nodes in solid spotweld nuggets tie to their layer only if the contact is defined with a node set not if defined by part PRIMER check has been modified to account for this e Case 10885 PRIMER now offers 2 connections options for keyout 1 to suppress write of all connections 2 to suppress connections which PRIMER has automatically created from weld data The latter is safe as all connection info can be re created from the welds the former option risks losing data and should be used with caution e Case 10846 Connection table default view now shows ID type subtype part id diameter layer 1 layer 2 layer 3 status error details e Case 10843 A new feature has been added to connection table which allows 2 or more welds that conflict i e are closer together than the user specified minimum separation distance to be merged by making a weld at the average position and deleting the conflicting connections If such a weld cannot be made the original connections will be restored e Case 10842 Show conx amp panels function off connection table has been modified to also unblank attached nodal rigid body or rigid body where these cause a connectivity error due to clash with constrained contact e Case 10719 A new option has been added to the connections table to remake spotwelds or bolts with their connection point position at the average position of the nodes
13. PRIMER Reading amp Writing Files e Case 10486 Because of the order in which panels were unmapped during a keyword output operation it was possible to click ahead while waiting for the file to finish writing If performed in a particular order such impatient clicking could generate an illegal sequence of commands that would result in the user being locked out of the user interface with the X banned cursor symbol everywhere The code has been changed to prevent this Bugs fixed in release 9 3 RC2 e Case 10403 When a Nastran file is written out PRIMER converts spotweld beams to solid spotweld CHEXA elements These were sometimes generated with ill conditioned topology resulting in negative volume A fix has been added so that all solid topologies will be properly defined with a positive Jacobian e Case 10360 A bug that would have prevented NODE_TRANSFORM cards from being written out unless NODE or NODE_RIGID_SURFACE cards were present has been fixed e Case 10321 PRIMER was not able to read ELEMENT_SHELL_BETA_OFFSET on keyword input This has been fixed in PRIMERSY 3RC2 e Case 10313 The Nastran reader would fail if there was no continuation character in column 73 for CHEXA elements Nastran required them when the reader was written but does not now This has been fixed for CHEXA e Case 10252 PRIMER would not write PART_ADAPTIVE_FAILURE cards to output files This has now been fixed e Case 10242 Mode
14. Windows and Linux platforms where the system dynamic memory routines are capable of returning released space to the system wide free memory pool PRIMER will now release this memory if it is able to do so However on Unix platforms where once memory is allocated to a process it cannot easily be released there is no change in behaviour since it would not bring any benefits Ove Arup amp Partners Ltd Pg 63 Oasys Suite v9 3 30 August 2008 Release Notes Oasys LS DYNA Environment Software Section 2 Oasys PRIMER Miscellaneous This is only a partial solution since memory for a given storage class is only freed if all leased space has been returned which means in practice only when all models have been deleted from memory The extra effort required to identify chunks of memory that could be freed when only one of two or more models has been deleted would be prohibitive e Case 8338 PRIMER now has coding to trap fatal system errors such as divide by zero segmentation violation etc which would previously just have terminated execution with only a core dump to show for one s efforts The code has been re organised so that the stack frame at the initial top level is saved and if any of these errors are encountered it makes a long jump to this saved frame discarding the current frame making continued execution possible The user is offered various options including attempting continued execution with the warn

18. elements remained those of their original part and did not acquire the colour of their new one This was because setting an explicit colour by part propagated this explicit colour down to the elements of the part effectively fixing it This behaviour has been changed so that setting explicit colours by part now sets the part to that colour but propagates to the part s elements as use parent part s colour the default behaviour The resulting colour change appears the same but if the elements are subsequently re parented to a different part then they will draw in the new part s colour because of this use parent logic Note that setting an explicit colour by element as opposed to by part will effectively fix the colour of the element so that it does not inherit its parent part s colour This distinction is both deliberate and correct e Case 11007 The display of BOUNDARY_PRESCRIBED_MOTION was a bit misleading for the rotation about a remote axis options DOF 10 11 12 This has been improved so that the arrows now show the appropriate motion vector at each affected node e Case 10991 When input is restricted to a single window the banned cursor X becomes current in the drawable part of all other windows However window management and also dynamic viewing commands are still possible Following dynamic viewing shift ctrl mouse button in a graphics window the cursor was not returning to the banned curs

21. fixed we are not entirely sure why the fix which is to force some extra synchronisation should work e Case 11587 On some Unix Linux platforms it would sometimes be the case that listing boxes would be empty when first mapped Any sort of window management event would then populate them This has now been fixed e Case 11586 On most Unix and Linux systems the file selector box would fail to respond to a window close request X button on Linux although Cancel would work correctly On older 2 4 kernel Linux platforms only the effect was worse in that such a close would delete the file selector box but not return control to the main PRIMER window resulting in a freeze of the whole application which would have to be killed and restarted These problems were related and have now both been fixed on all Linux and Unix platforms the file selector box now closes properly and control also reverts correctly to the main programme e Case 11500 On platforms that use X11 window managers i e Linux and Unix it could sometimes be the case that listing boxes containing text such as help and explanation messages would appear partially or fully blank in PRIMER Performing any sort of window manager operation on the box would then result in its contents appearing This has now been fixed e Case 11407 This is logged against PRIMER but since it is a menu system problem it can affect all programmes Whe
22. for deletion the connection is also flagged making it look as if it is to be deleted However the default CONX_ACTION is not to delete the connection but rather to empty it so the rather confusing situation arises that A connection appears in the to be deleted list But it does not get deleted And the for why was this locked does not give a good reason This has been fixed by changing the internal logic so that when connections are flagged in this way but will be emptied rather than deleted they no longer appear in the to be deleted list A final problem found was that in a model with realised connections if the intrinsic part of the connection i e that used to create the welds bolts etc was deleted then the connection itself was correctly also listed for deletion However if the user chose to deselect the connection and apply the remainder then the part and its elements were still deleted leaving the connection referring to a non existent part via a corrupt label This has been corrected by ensuring that overt as opposed to implicit membership of a connection locks such members against deletion e Case 11579 When using CLEANUP UNUSED if a Nodal Rigid Body was eligible for cleanup because all its node had been deleted then this was duly carried out However if any Boundary Prescribed Motion or some Initial cards referred to the nodal rigid body then either these would lock it against cle

52. ET_SEGMENT cards was that if only a subset of a solid or thick shell part was selected it would create segments on the exposed faces despite the fact that these were topologically internal Therefore this has been revised to give three options 1 External faces the default Only faces on the selected elements which would be externally visible were all elements of this type to be unblanked are coated In other words only element faces that are topologically external 2 Exposed faces Faces which would be exposed were only the selected elements to be unblanked are coated This was the original behaviour 3 Visible faces Only faces on the selected elements which are currently visible on the plot are coated This is intended for view factor calculations where only facets visible from a given viewpoint should be selected and it is unlikely to have an application in normal structural analyses The same options have also been made available in the COAT PART panel Ove Arup amp Partners Ltd Pg 13 Oasys Suite v9 3 30 August 2008 Release Notes Oasys LS DYNA Environment Software Section 2 Oasys PRIMER Connections Connections This section contains cases related to both Connections in the PRIMER sense cases and also those referring to welds of he various types available Enhancements made in release 9 3 e Case 12057 Added in command line writing out of connections files for all connections in th

IMER Editing e Case 9744 If multiple models had been read in but only a single model was active in Model List then it was still necessary to prefix item numbers with a Mn prefix when typing explicit labels into text boxes in contexts such as Measure etc This has now been fixed is only a single model is active then regardless of how many models are in the database the Mn prefix of the single active model is assumed automatically e Case 7120 Auto node selection in element create menu has been significantly improved when picking nodes on solid meshes Bugs fixed in release 9 3 RC2 e Case 10612 In editing panel fields for load curves or tables a precision error could occur if an integer value of 8 digits length was typed in For example label 40000022 would be altered to 40000024 This would only occur if values were typed in and only if they were extremely large Selection of curves from the popup menu was unaffected This has now been fixed e Case 10603 In the ELEMENT editing panel the COPY_EXISTING button would appear to work but would in fact do nothing and just reset the element to its original pre edited state This has now been fixed e Case 10595 In the INCLUDE_TRANSFORM panel the Set all offsets to text box acted immediately to reset all values if used This meant that someone tabbing through the panel from text box to text box could accidentally use it and reset everything by mistake The pane

MIG weld issues The ergonomics of applying these need improvement the proximity check should be turned off when making them buttons for invalid creation methods require removing from the panel and a more user friendly method of welding along a free edge is required currently a node set is required This capability is still under development Contact penetration checking e Case 12098 When using Contact penetration checking the number of penetrations reported for a given MAXPAR value is not exactly the same as that from LS DYNA However the number of penetrations obtained from SMP and MPP versions of LS DYNA also varies for this model so it seems likely either that the model in question is ill conditioned or that the detailed geometry of penetration checking has varied between LS DYNA releases Ove Arup amp Partners Ltd Pg 88 Oasys Suite v9 3 30 August 2008 Release Notes Oasys LS DYNA Environment Software Section 2 Oasys PRIMER Known Bugs in v9 3 e Case 12167 If SHLEDG 1 on CONTROL_CONTACT and SOFT 2 on CONTACT then the shell edges are projected as square The effect of this is not accounted for in contact penetration plots This problem is still under investigation Graphics e Case 8237 Element triads do not take into account any local orientation defined on the material card via AOPT etc or on the element itself via BETA etc They are purely geometrical and based on the element topology Mate

POTWELD_BEAM card can lead to a crash in PRIMER Corrected now Bugs fixed in release 9 3 RC2 e Case 10247 Where TIED contacts are defined by segment set then both conventional contact penetration checking detecting tied nodes and attachment via tied contact in FIND_ATTACHED would fail to work properly Both problems have now been corrected e Case 10211 Edit of existing contact which did NOT have _ID set showed the contact as if it did have _ID This has been fixed to show the correct contact status Case 10098 There was an error in the contact penetration check which would lead to contacts on solitary 3d elements i e those on which all faces are external being ignored There was an additional minor error compounding the above which meant that tied and tiebreak contacts were not treated as pure attached at nodes type contacts for all aspects of checking These have been corrected However for the vast majority of models in which solitary 3D elements do not occur neither of these two errors would have any effect on the outcome of a contact check e Case 9748 PRIMER contact sketch function was sketching whole model when contact type was undefined This has been changed so that nothing is sketched until the contact type has been defined e Case 8750 Option has been added to limit contact penetration count to unblanked elements This has 3 advantages It means that the check can be substantially quicker as all elements outside
64. PRIMER thought that include files had changed The behaviour has now been changed If PRIMER makes connections during model checking a special flag is set on them In model modified these connections are silently ignored However if instead of doing a model check the user presses the Connections button then PRIMER assumes that you actually want connections and so the connections that PRIMER makes will NOT have the special flag set on them so PRIMER will flag them as differences in model modified Bugs fixed in release 9 3 RC2 e Case 9958 Model Modified could crash if a model contained certain DATABASE cards This has now been fixed Orient Bugs fixed in release 9 3 e Case 12181 Copy orient function was incorrectly copying the contact when the same part option was set This is now fixed e Case 11922 PRIMER would orient INITIAL_FOAM_REFERENCE_GEOMETRY This has now been changed and now PRIMER will NOT orient it The only thing that could cause problems is scaling and so a warning is now given if the user tries to scale INITIAL_FOAM_REFERENCE_GEOMETRY e Case 11660 When multiple orient drag operations were undone using the Undo function PRIMER was only applying the inverse translational transform of the last translation Whilst this does not affect coordinates as these are restored forcibly on undo it meant that for example undoing the orient of a DEFINE_VECTOR that had been multiply dragged did not work properly

247. y labels are now drawn in the standard not background colour e Case 11845 On platforms using PBuffers for refreshing the graphics window typically Linux the graphics of shell based items sketched on top of the current image could occasionally omit approximately half the elements The bug was noticed following a sketch of a layer from the connections panel but it could probably crop up in any context where shells are sketched on a model in which the highest numbered part contains solids or thick shells This was because of the graphics driver getting stuck in back face culling mode used to draw 3D elements so that shells sketched subsequently would only be drawn if they faced the user Rotating the view would reveal different faces This has now been fixed e Case 11805 If connection visibility was turned on in the Entity panel then connections were drawn correctly however an Autoscale operation failed to take them into account when re computing the graphics scale This has now been fixed e Case 11782 When Model Copy is used inside PRIMER any part colours in the source model are lost as the target model reverts to the standard PRIMER colour scheme This is inconsistent with the behaviour when a model file is written out and read in again which preserves colour and transparency information Model Copy has therefore been modified so that non standard part colour and transparency data are copied to the target model e
248. y s assemblies e Case 10060 When creating child definitions for a mechanism the default is now to have all three translational degrees of freedom coupled Previously none was set and the user had to specify something in order to make the definition In addition the various dummy and mechanism child editing creation panels assemblies connections points children now all adhere to the standard PRIMER logic that definitions which are missing are highlighted in red and references to latent items are in light blue e Case 8711 If a FMH headform is not in the zero rotation position but rotated to a certain position through the FMH functionality Primer will now test for this before any automatic positioning process and take it into account e Case 7602 Primer now has improved FMH positioning functionality The main additions are an automatic vertical angle positioning tool which will rotate the headform until the chin touches the trim and then rotates back by 5 10 degrees or some other user defined value It is also possible to set a positional node that can be used for automatic headform positioning and headform rotation This node is used as the reference point rather than the headform reference node Enhancements made in release 9 3 RC2 RC2 e Case 10868 The command line and therefore also batch MECHANISM and DUMMY commands now have a top level POSITION command that allow a previously saved position to be restored e Ca
