14.0 API Programmer's Guide
Blocks to Sets and Boxes
The Radioss keywords /GRBEAM/BOX/, /GRBEAM/BOX/, /GRBRIC/BOX/, /GRNOD/BOX/, /GRQUAD/BOX/, /GRSH3N/BOX/, /GRSHEL/BOX/, /GRSPRI/BOX/, /GRTRUS/BOX/, /LINE/BOX/ and /SURF/BOX/ (including /BOX2 keywords) have been mapped from the block entity to the set and new boxes entities. Other keywords of this family are mapped to sets. See Sets and Boxes data names documentation for more details.
Scripts that created or queried the block entity for these keywords must be updated to use the sets and boxes entities. To create one of these keywords, both a set and a box entity are required. The set then refers to the box entity. Below are a few examples.
*createentity boxes config=2
*createentity sets cardimage=GRSHELL
*setvalue sets id=$set_id ids={boxes $box_id}
*setvalue sets id=$set_id STATUS=2 900=1
*createmark boxes 1 "by id only" $box_id
*rigidlinkbycollector $masterNode boxes 1 123456
command.tcl
HyperWorks Desktop no longer writes out command.cmf, which utilized the legacy command file syntax. Instead, it now writes command.tcl using standard Tcl syntax. The contents of this file are the same as before. Only the syntax has changed.
- Added a new command line option -nowriteviewcommands and Tcl command hm_writeviewcommands to disable writing of certain view commands to the
command file. Also added a new hm_info option writeviewcommands to
query the value. The list of view commands affected by this is:
- *rotateabout
- *view
- *view_restoreprevious
- *viewset
- *window
- Added a new environment variable HM_COMMANDFILE_DIR to control where the command file is read/written. A value of ./ replicates the current behavior of the start-in directory. Other values indicate an explicit directory.
- Added a new environment variable HM_COMMANDFILE_MODE to control the behavior of the command file. A value of APPEND replicates the current behavior of appending to any existing file. OVERWRITE deletes any existing file and creates a new one. UNIQUE creates a uniquely named command file per-session.
- Added a new command, hm_getcommandfile that returns the path and file name of the current command file.
Current Collectors
In order to properly support the modules/parts modular workflow, it is required that when importing any file (CAD, FE, HM binary, etc.) the current collectors are not changed. This applies to components, includes, load collectors, modules/parts, system collectors, and vector collectors. There was an inconsistency in previous releases where sometimes this would be changed on import. Now, the current collector will never be changed during the import of any file. It may be necessary to review and update any scripts that expect this behavior.
Groups to Constrained Extra Nodes
The LS-DYNA keywords *CONSTRAINED_EXTRA_NODES_NODE and *CONSTRAINED_EXTRA_NODES_SET have been mapped from the group entity to the newly added constrainedextranodes entity. See the constrainedextranodes data names documentation for more details.
Scripts that created or queried the group entity for these keywords must be updated to use the constrainedextranodes entity. Below are a few examples.
*createentity constrainedextranodes config=101 compid=$comp_id entityid={nodes $node_id}
*createentity constrainedextranodes config=102 compid=$comp_id entityid={sets $set_id}
Groups to Cross Sections
The LS-DYNA keywords *DATABASE_CROSS_SECTION_PLANE_ID and *DATABASE_CROSS_SECTION_SET_ID, the Radioss keyword /SECT have been mapped from the group entity to the newly added crosssections entity. See the crosssections data names documentation for more details.
The Radioss keywords /SECT/CIRCLE and /SECT/PARAL, and the OptiStruct keyword SECTION are newly supported with the crosssection entity.
Scripts that created or queried the group entity for these keywords must be updated to use the crosssections entity. Below are a few examples.
*createentity crosssections config=101
*createentity crosssections config=102
*createentity crosssections config=201
*createentity crosssections config=301
History Undo/Redo
Support for multi-level undo/redo has been added for many panels in 14.0.
- *rejectmark will reject multiple steps in the history, if any exist, and is no longer limited to just the last action. So it is important to keep this in mind and update any scripts to not call this command unnecessarily.
- If history is turned off, *rejectmark is only supported for certain commands that still use the legacy reject mechanism. It will not work for commands that use the new undo/redo mechanism. The solution is to enable history again, for a minimum of 1 action.
There are a number of new commands added to support undo/redo, as listed in the New Commands section.
These provide information on the commands that are enabled for undo/redo support. Additional commands will be supported in future releases.
*startnotehistorystate "Multi operation history action"
*createmark elems 1 1-100
*deletemark elems 1
*createmark elems 1 101-110
*maskentitymark elements 1 0
*endnotehistorystate "Multi operation history action"
This
will show as a single undo/redo action with the name "Multi operation history action".Any calls to *rejectclear clear the entire history. It is therefore important to remove such calls unless they are absolutely necessary.
You can begin to update your Tcl scripts with these in mind, even though they will not have any effect in 14.0.
Modules/Parts
For the 14.0 release, there are only a limited set of APIs available for creating, modifying and querying modules/parts. You will notice that when certain operations are performed (for example, import BOM, add/modify representations, and so on), nothing is written to the command file. This is intentional for the 14.0 release. A complete set of APIs, including full documentation, will be available in 14.0.110.
Parasolid Import/Export
In HyperWorks Desktop 2020.1, all Parasolid import and export now utilizes the native Parasolid libraries. There is no longer support available for using the third-party Parasolid import or export capabilities.
- #ct\parasolid_reader -> #parasolid\parasolid_reader
- #ct\parasolid_writer -> #parasolid\parasolid_writer
- The native Parasolid reader or writer will automatically be used.
- The command file will contain the updated syntax. Scripts should be modified using this modified output.
This is to allow for compatibility with older scripts. While this compatibility is maintained for the 14.0 release, it may be removed in a future release. Therefore, it is recommended to modify scripts to use the native Parasolid reader and writer names during this limited transition period.
Undefined Entities
- If Defined is inactive, the entity not will be written to the solver deck.
- If Defined is active, the entity will be written to the solver deck.
The export status of undefined entities cannot be changed.
If a solver deck contains undefined properties or materials, HyperWorks Desktop creates the appropriate entities and assigns a default card image upon import. The Defined state, attributes, and card image can be modified as per requirements of the user.
- Query the materialid or propertyid data names, and then use hm_entityinfo exist to check if that particular entity exists.
- Compare the materialid or propertyid data names to the material.id or property.id data names to check for entity existence.
As undefined entities are actual entities in the database, this logic will no longer work as both cases will report that the actual entity exists. Depending on the use case, you may need to additionally check if the entity is defined or not. This can be done by using hm_getvalue to query the definedentity data name.
hm_getvalue mats id=100 dataname=definedentity
