1. Selection e Case 16455 Predictive picking has been added to D3PLOT For quick pick and other menu based picking the default is now to show what would be picked were you to click This can be toggled on off using the PP button at the top of the screen or by the p short cut Quick pick and menu based picking are controlled separately Hovering over a row in a menu of items to be selected will also now sketch the items in question Again this can be controlled The use of the ambiguous menu is now also switchable and if used it too will show the item to be selected when the cursor is hovered over a menu row All these options may be initialised via preferences 1 Ove Arup and Partners Limited June 2011 Page 113 OASYS LS DYNA ENVIRONMENT SOFTWARE RELEASE NOTES VERSION 10 Shortcut e Case 15288 A shortcut k has been added which resets all entity visibilities to what they were at start up Speed e Case 15525 It has been a criticism of the code that it runs slowly when multiple models are loaded To some extent this is inevitable as more demands are made on memory cpu and graphics but a lot of changes have been made to try to improve matters Remove redundant operations when dealing with multiple models in a window e g blank in M1 does not require a visibility update pass in M2 and M3 The results database logic has been modified so that it is less parsimonious about storage meaning
2. The Mechanism joint capability in Primer has been enhanced to permit the connection points used by joints to be defined by explicit coordinates as well as nodes Previously only nodes were permitted A joint can use any permutation of nodes and coordinates and various means of defining coordinates are provided including find centre of hole in mesh average coordinate of a list of nodes centroid of a part etc As a consequence the CONNECTION keywords in MECHANISM after main 1 Ove Arup and Partners Limited June 2011 Page 85 OASYS LS DYNA ENVIRONMENT SOFTWARE RELEASE NOTES VERSION 10 deck END have been extended This extension is backwards compatible so Primer V10 will read decks from an earlier version but not forwards compatible e Case 12659 A mechanism line joint can now have an optional third assembly that is forced to slide a user defined fraction of the sliding distance of Assembly 2 along the joint This could apply for example to roller bearings in seat rails e Case 11761 Mechanism connection movement can be specified by typing in slide distance or angle e Case 11486 The ability to colour parts by mechanism assembly number has been added to the mechanism positioning panel This is optional and the user can toggle back and forth between assembly colours and default part based ones at will Also if this mode is chosen then colours revert to their default on exit from the positione

4. BLANK UNBLANK ONLY for sketchable items e Case 14631 Titles in editing panels show no title defined if the original item has not been given a title and historically this string has to be removed out by the user in order to define a new title Primer now recognises this as a special case and clicking in the title box where such a message is displayed will automatically remove the message so that the new title can be entered immediately e Case 11290 Axes of rotation in the INITIAL_VELOCITY_GENERATION editing panel can now be defined quickly by selecting two nodes The DEFINE_TRANSFORMATION editing panel has been enhanced to allow the definition of transformation distances points etc by selection of one or two nodes in the model Write e Case 17186 A preference has been added to suppress writing item referenced but not explicitly defined warning messages to a model upon keyout e Case 15429 A new keyout option for include files has been added This will write all includes to the same directory as the master file e Case 14494 The output panel now displays the root name of the sub directory to which includes will be written and allows the user to edit it 1 Ove Arup and Partners Limited June 2011 Page 99 OASYS LS DYNA ENVIRONMENT SOFTWARE RELEASE NOTES VERSION 10 4 2 D3PLOT 4 2 1 Enhancements in 10 Attached e Case 15193 A find attached function has been added into D3Plot accessed thro
5. Curves can now be sorted alphabetically by label in the curve manager Read e Case 15304 In version 10 0 the option to read multiple ISO curves now scans the contents of the index file and builds a list of all the available channel files The user can then select which channels he wants to read instead of reading all of them Since the filenames are not much use the user can choose to either display the filenames or the ISO channel names e Case 14462 Version 10 0 of T HIS now supports the TRHIST ASCII database file generated by LS DYNA that contains information for tracer particles defined using the DATABASE_TRACER option User interface e Case 16287 From version 10 0 onwards the EDIT menu has been modified so that once you have started to edit a curve you are locked out from the other T HIS menus dynamic viewing will still work until you either exit or quit from the edit operation This has been done to stop users deleting modifying the contents of a curve that is also being edited e Case 16021 Version 10 0 of T HIS has been modified so that if you are working with multiple pages and you change the page the list of active graphs is automatically updated to the graphs on the current page Any changes the user makes will then only apply to the graphs the user can see The option to select all the graphs can still be used after changing page if the user wants to update modify all the graphs including any not on the curren
6. This is done on update by creating or modifying a CONSTRAINED_NODAL_RIGID_BODY or by creating CONSTRAINED_EXTRA_NODES as necessary Formfx e Case 11843 The FormFX tool now allows the selective mapping of the following data from the forming model to the crash model Initial stress tensors initial strain tensors plastic strain and shell thickness e Case 4112 Primer can now map forming data on to parts in the crash model that are mirror images of the parts in the forming model e Case 4039 Nodes lying on the forming model and the crash models can now be picked easily from the graphics window in quick succession The re designed panel allows the picking of nodes in a manner similar to that in the ORIENT gt TRANS ROT tool e Case 4037 The FormFX tool now allows the selection of multiple parts for mapping data between the forming and the crash models The panel has also been re designed to make it more intuitive Geometry e Case 14187 IGES line data can now be visualised in Primer e Case 13308 IGES CAD files can now be read into Primer Graphics e Case 16717 When drawing SET_GENERAL if BOX or DBOX is set Primer will now draw the boxes referenced e Case 15963 PRIMER now has a capability to limit the number of labels drawn on the screen if labels for a large category are turned on in the Entity panel The user can choose whether not to apply this setting the maximum number of 1 Ove Arup and Partners Limit
7. When a user working on windows selects to use Unix format for the keyout of include file names i e drive mapping from windows to unix Primer will now automatically use unix format line endings for the files written This obviates the previous need to set the ascii_file_format pref e Case 15363 Keyword output of an input deck containing many CONSTRAINED_TIED_NODES_FAILURE cards in the default classic output sequence can be slow This is because each tied nodes definition references a separate set which is written out immediately after it and the lookup of this requires a search which can be slow This has been speeded up for this case and also other keywords where the situation might occur of many keywords each referencing one of many sets Ztf e Case 16708 When a ztf file is written automatically on keyout pref setting the name and directory was being derived from the last file keyed out This did not work well for models with includes The code has been corrected to derive the name directory from the master file as utilities function ztf keyout does e Case 15170 If CONTROL_SPOTWELD_BEAM is used to convert any spotweld beams into single solid element spotwelds then the spotweld beams are not written to the ZTF 1 Ove Arup and Partners Limited June 2011 Page 48 OASYS LS DYNA ENVIRONMENT SOFTWARE RELEASE NOTES VERSION 10 file Instead it contains a spotweld solid data block with the spotweld soli

9. 10 e Case 15274 SECTION_POINT_SOURCE Two more rows for orifice nodes are added to the editing panel to allow users to keep track of five orifice node rows at a time e Case 14984 Intial velocity fields VX VY and VZ are made available in INITIAL_VOLUME_FRACTION_ GEOMETRY card e Case 13714 Primer now includes an editing panel for LOAD_THERMAL_VARIABLE_BEAM e Case 13375 When creating or modifying materials it is now possible to sort the list of material types by alphabetical order Kwd editor e Case 16633 Text popups are now available for editing char string fields in the SENSOR keyword editor e Case 16079 The Options button in the keyword editor s top row is used to select rows and perform other operations but this is not obvious to a new user of the panel Therefore it has Been changed to white text on a blue background to make it stand out Modified so that both a left mouse click original behaviour and a right mouse click new will invoke its associated popup menu with the latter being made more obvious by the v symbol on the button Hover text giving a brief explanation of its function has also been added e Case 15698 The keyword editor can now be displayed without its Entry row which is useful when it is used to display information rather than in a context where manual editing and data insertion are likely to take place It is also now possible for two keyword editors to co
10. 16398 Primer no longer treats solid spotwelds tied to a shell part with CONTACT_TIED_SHELL_EDGE_TO_SURFACE as an error although CONTACT_TIED_NODES_TO_SURFACE is preferred e Case 15844 When creating connections sometimes the labels of the FE entities created may not re use labels used in previously deleted connections This has been fixed e Case 15752 When reading a custom weld file there is the option to ignore part data which should enable welds to be made even when no part information is provided This ability lost in 94 has been restored For spotweld beams the layer data for the connection will be constructed from the shells to which the beam attaches e Case 15706 If beams on a connection entity have their ELEMENT_BEAM_PID s in the incorrect order a warning message is given If the user manually tried to fix this through the ELEMENT_BEAM edit panel the connection definition could be incorrectly modified as a result This has been corrected e Case 15592 When Primer creates connections for existing MAT100 welds in a model in which the spotweld contacts already exist the contact checker is used to ensure that the tied part is used in the layer definition not a part that may happen to be coincident with it If however a spotweld attaches to duplicated shell the choice of candidate shell is ambiguous in LS Dyna and may not be the shell of the part actually in the contact To be conservative Primer will select the t
11. Also to see what constitutes the slave and master in a contact a colouring scheme is available which plots slave in green and master in red This colouring option is available under Display gt Colour gt Contacts Contour e Case 17203 When contouring element formulation Primer will now consider CONTROL_IMPLICIT_EIGENVALUE settings e Case 15096 You can now plot plastic strain on the INITIAL_STRESS_SHELL card by integration point and also plot max and min values e Case 14306 Initial velocity vector components and magnitudes of initial velocity vectors can now be contoured in the CT SI mode e Case 12354 Various element quality metrics as well as an overall quality value can now be contoured in Primer Cut section e Case 16509 If a cut section is active then it is possible that when a new model is read in it will be clipped out entirely and not visible if it does not intersect the cutting plane or lie on a visible side of it This is correct but it can be disconcerting since it appears that something has gone wrong with the graphics or that the model has not read in correctly Therefore PRIMER now checks to see if a newly read model is totally clipped out by an active cutting plane and it is then it issues a warning and offers to turn the plane off or move the plane origin to the centroid centre of the bounding box of the model The user is free to take either action or to take no action at all and sort the p
12. Case 16186 If some existing category of displayed items eg shells was turned on or off in the ENTITY panel and then a short cut key eg S for Shaded or an explicit drawing command were used to redraw the image then screen picking of the changed items could be wrong If they had previously been displayed but were now turned off then it might still be possible to screen pick them conversely if they had been turned off then on again screen picking might fail to select them Changing display modes eg LI following by SH or using UPDATE on the ENTITY panel would fix this problem This was due to failing to consider correctly all situations in which the internal table of is visible on the screen and hence eligible for screen picking needs to be updated One such situation was a change in the entity switch status for items and this has now been corrected 1 Ove Arup and Partners Limited June 2011 Page 45 OASYS LS DYNA ENVIRONMENT SOFTWARE RELEASE NOTES VERSION 10 Sets e Case 16713 In models with SET_GENERAL GENERATE definitions for a rigorous test of whether or not a node is in a set primer needs to build data tables which requires decomposition of every such set To ensure the data is always up to date when required the tables will always be rebuilt if any operation has occurred which has updated the data of the model e g update on an edit panel On a very large model with many SET_GENERAL this may prove an
13. In doing this the selected items relative hierarchy is maintained 1 Ove Arup and Partners Limited June 2011 Page 123 OASYS LS DYNA ENVIRONMENT SOFTWARE RELEASE NOTES VERSION 10 6 Multiple items can be translated around the page by dragging 7 When using the resize handles on an item when multiple items are selected the other items are resized according to the relative size to the master item Preferences e Case 15529 Added preferences to allow the user to specify the format of the default DATE and TIME variables e Case 13817 Snap size grid size and nudge distance have been added as preferences to reporter Scripting e Case 9031 The output from a library program can now be written to a variable Shortcut e Case 9333 The p key can now be used to flip between design view and presentation view Tables e Case 15546 Any drag operation on a table item forced a recalculation of the column widths row heights Two changes have been made 1 Column widths row heights are only recalculated if the drag event is due to the resize handles not just a drag translate 2 If you do use the drag handles then the widths heights are recalculated based on change in size of the table i e the relative size of the column widths row heights is maintained e Case 15319 It is now possible to set the background colour of cells in tables Unicode e Case 15436 Reporter can now read unicode arguments e g variable
14. RELEASE NOTES VERSION 10 User interface e Case 16964 When using the Menu Attributes panel to change display factor or font sizes the text in GUI buttons changes size but that in dialogue and listing boxes does not Although it will be resized when the Primer session is restarted This has been corrected so that dialogue listing box text will now resize dynamically allowing a better impression of what the final appearance will be e Case 16500 A new preference has been added code name checkpoint_dir directory or none If a pathname or directory is given then checkpoint files will be written there instead of in the default location If none is specified then checkpoint file output will be suppressed e Case 15845 There was a bug in the graphical user interface which meant that if a listing box eg help text check output etc was created and the horizontal scrollbar was used to move across to the right then this scrollbar position was remembered the next time the same listing box was used This not only looked a bit odd but also if the old text was wide but the new text was narrow then scrolling far to the right could result in nothing being visible This has been corrected e Case 15361 When using the keyword editor the sequence Highlight several rows Click in a text box somewhere in a highlighted row Without making any changes click elsewhere Resulted in the equivalent of lt enter
15. The gt T HIS button at the top of the XY PLOT window will now start the T HIS D3PLOT link if it is not already running Ztf e Case 16043 From version 10 0 onwards the optional additional files that D3PLOT reads can be specified on the command line ztf ZTF_file group ASCII_group_file prop properties_file set settings_file In addition to specifying these on the command line the Open Model menu has been modified to allow the user to select alternate sources for these files e Case 4399 From version 10 0 onwards the Entity Panel now contains an option to display names as well as labels If a ZTF file is read in containing the names of elements nodes rigidwalls joints and parts then these can now be displayed as well as the ID s 1 Ove Arup and Partners Limited June 2011 Page 117 OASYS LS DYNA ENVIRONMENT SOFTWARE RELEASE NOTES VERSION 10 4 3 T HIS 4 3 1 Enhancements in 10 Data access e Case 16602 Version 10 0 of T HIS now reads DBFSI data from the BINOUT LSDA file e Case 16559 T HIS 10 0 can read the optional TRHIST ASCII file and the TRHIST data written to the LSDA binout file by LS DYNA 971R5 and later e Case 15518 From version 10 0 onwards the routines that extract data from the LSDA binout file have been modified to make them faster when reading data for multiple items in one read operation Reading data for one entity at a time or multiple data components for a single entity won t be any
16.
