2. Oasys LS DYNA Environment Release Notes Version 9 4 2 2 Bugs The enhancements and bug fixes for each program have been broken down into a series of topics Within each topic enhancements and bug fixes are listed by case ID most recent first 2 1 Oasys PRIMER 2 1 1 Bugs Fixed in 9 4 2 Assembly e Case 15916 Recursive subset definitions are illegal in Primer If a model was read which contains them Primer was liable to get stuck in a loop when part tree assembly button was accessed or otherwise A necessary break out has been added e Case 15769 The name of the group could be lost when reading ANSA comments in a Dyna deck and converting to Primer assemblies This has been corrected e Case 15707 Use of extra data files in model build was not working correctly giving the error cannot find include file relative to root This resulted from an error constructing the include_path definitions for model build Belts e Case 16081 It was found that 1D seatbelts can give the wrong force transfer across sliprings in LS DYNA if the topology numbering of the seatbelt elements is not sequential in the elements attached to the slipring This means that the topology ordering N1 belt 1 N2 Slipring N1 belt 2 N2 will give the correct results but N2 belt 1 N1 Slipring N1 belt 2 N2 will not In other words seatbelt elements must all have sequential topology in the order N1 gt N2 N1
3. e Case 14656 A hanging window was left after using CrossSection Create from JavaScript Selection e Case 14785 The feature line picking of nodes worked correctly for nodes picked on the surface of a 2D mesh of elements but wrongly on a mesh of 3D element This was due to an internal error selecting and then propagating the correct 3D element face Sketch e Case 14805 The sketch function for DEFINE_ BOX when applied to boxes with ill conditioned definitions i e MAX lt MIN was failing to show that the box was effectively flat User interface e Case 14701 In the top level tools panels e g MATERIAL in Primer the message shown when nothing had been selected for the current operation e g modify was nothing defined This was misleading since it made it appear that no definitions of the relevant type existed whereas what it should have said was nothing selected So it has been changed to that Page 22 Ove Arup amp Partners Ltd 19 October 2010 Oasys LS DYNA Environment Release Notes Version 9 4 2 Write e Case 14782 Primer could incorrectly keyin or incorrectly keyout BOUNDARY_FLUX cards if the number of extra constants contained on the card was exactly divisible by 8 2 1 3 Bugs Fixed in 9 4 Airbag e Case 13931 PRIMER would give an error message if the IDA and ADG fields on a AIRBAG_ALE card referenced latent parts This is however valid e Case 13930 When orienting the parts

6. All parameter expressions are then re evaluated using the possibly updated scalar parameter values Since expressions may use other parameter expression values this process iterates until no further changes are found The resulting parameter expression values are then tested against original value any units factor and if this still differs then they are modified to give Page 96 Ove Arup amp Partners Ltd 19 October 2010 Oasys LS DYNA Environment Release Notes Version 9 4 2 multiplier so as to achieve the required value Finally all parameter expressions are re evaluated iteratively once more to reflect any changes arising from step 3 In a well constructed model in which parameter usage is consistent with respect to the underlying units of values this should result in the associating between parameters and the data fields in which they are used remaining the same However if the changes applied above result in a disparity between the value of a data field and the parameter it references then PRIMER will remove this association e Case 12781 LS DYNA 971R3 will apply parameters in the negative sense if the syntax amp xxx is used so PRIMER has been updated to comply with this When output for versions prior to 971R3 is chosen a warning message is issued and the numerical equivalent of the ve parameter value is written instead Part table e Case 13939 Minimum timestep and minimum element size have b
7. Reference Node with the same model being shown in multiple windows when a different reference node had been requested in each window In D3PLOT 9 3 this did not work correctly all windows would display as if a single reference node had been defined There was no problem with different models each in a different window with a different reference node for each model The problem occurs only when different reference nodes are used in different windows for the same model Each window on a model will now show the correct reference node settings should they be different When WRITE and XY_DATA give results e g displacement relative to the reference node be careful not to use different reference nodes in different windows for the same model in this case it may be hard to predict which reference node will be used to calculate the WRITE or XY_DATA results The same fix and comment applies to the three nodes used for Shift Deformed Cut section e Case 14257 Two errors have been identified in the processing of cut section forces through beam elements 1 When beams did not have any orientation node which is legal for circular sections then D3PLOT was failing to calculate a local axis system for them and reverting instead to a unit matrix effectively orienting such beams for the purposes of cut section forces in the global axis system If no third node is defined then the long X axial axis N1N2 is now computed correctly and th

HIS D3PLOT normally writes log output to a console window However some security software can prohibit applications from opening a console and this can stop the software from running Therefore a eo filename command line argument has been added which will suppress the console window and instead send log output to a file The environment variable OASYS_ NOCONSOLE will have the same effect Keyword e Case 14867 INTERFACE_SPRINGBACK cards followed by a list of nodes were being incorrectly read as multiple Interface keywords due to an error introduced into 9 4 e Case 14637 When type was changed from node set in edit panel for CONSTRAINED_EXTRA_NODE the entry was not being cleared This could result in a SIGSEV if one then tried to edit the entry The old entry is now cleared when the type is changed Page 18 Ove Arup amp Partners Ltd 19 October 2010 Oasys LS DYNA Environment Release Notes Version 9 4 2 Kwd editor e Case 14454 The BOUNDARY_NONREFLECTING_2D keyword editor no longer gives spurious error that the node set it refers to is not defined e Case 12827 It is now possible to bring up the generic keyword editor for DATABASE_HISTORY_NODE_LOCAL from the Part tree in CONTENTS mode Macro e Case 14949 Recording a macro could record the wrong popup window number if a popup window used hover text e Case 14941 Macros could sometimes not play back correctly for button presses if the press would map a win
11. Merge the Cleanup and Delete buttons are greyed out to prevent this e Case 13657 If a model contained include files that were not read from a model scan and it was merged with another model the new merged model would forget that the include files had not been read e Case 13629 PRIMER could crash if merging models failed e Case 13275 If model merge would create out of range labels e g 9 digit shell labels a warning is now given and the user is given the option of aborting ignoring automatically renumbering or mapping the renumber panel after merging e Case 12649 Page 41 Ove Arup amp Partners Ltd 19 October 2010 Oasys LS DYNA Environment Release Notes Version 9 4 2 If copying a model e g using Model gt copy or Model gt merge master file information such as numbering ranges could be lost if the model did not contain include files Also model merge options have been added to allow the user to select which information to keep such as numbering ranges Mesh e Case 14118 PRIMER could incorrectly try to fix an element transition when using the fix transition tool if an element that did not need fixing was picked e Case 13513 Combining shells from the Mesh Split menu could sometimes produce a shell with a strange shape Additionally only 4 shells at a time could be combined This limit has been removed e Case 13316 When offsetting shell elements using the Mesh gt offset feature the offset ve

59. RIMER 9 3 1 could handle the specific cases of PGP encrypted data within MAT and DEFINE_CURVE keywords so long as a specific syntax was followed However it could not handle randomly occurring blocks of encrypted data in a deck In release 9 4 this restriction is lifted and randomly occurring free standing blocks of PGP encrypted data are now processed as follows During input they are copied verbatim to temporary saved pgp data files A separate file is used for the master deck and each include file During keyword output the contents of these files are copied verbatim as the last entry before END in the relevant files This implies that free standing encrypted data is both order and position independent within the input deck The position of the encrypted data within the deck is not remembered on output In cases where this order independent free standing logic is not valid users will need to encapsulate order dependent encrypted data within one or more include files and refer to them in the required order and possibly position from within the master deck e Case 12717 PRIMER now has the ability to read ANSA group comments can convert these to PRIMER assembly data The user can also select to write PRIMER assembly data out as ANSA comments upon keyout e Case 12681 PRIMER will now convert HM assembly comments into PRIMER Assembly data The user can also choose to write PRIMER assembly data as HM comments rather than P
