OptiStruct Interface 2021 Release Notes

OptiStruct Interface

New Features

Include File Drive Mapping

On import of solver decks that contain includes, HyperWorks now allows mapping from one folder path to another to import include files where the include path written in the solver deck doesn’t match the location of the files, which includes different paths due to different operating systems. Found in Preferences > Drive Mapping or in the Solver Deck import options, you can define the source path where the files reside and the target path as written in the solver deck and use this to successfully import files without the need to edit the include paths in a text editor.

Auto Contact Enhancements

Ease of component selection from graphics to detect contact automatically with specified tolerance.
Accept or Reject detected contact through contact traverse.
Review, modify contact pairs using advance selection.
Contact browser for advanced query the contact pairs created using auto contact.

String-Based Input

String-based labels offer easier identification of entries in the input file.
Labels can be used to identify entries via their corresponding ID field.
New solver option in export browser “Export as named entity” with free format export.
Labels export supported for Properties and Materials entity and their corresponding references.

Solver Browser Enhancements

You can create solver cards from the solver browser.
Cascading menu organized solver entity list.
Ease of creation with reduced panel dependencies.

Model Check Enhancements

Check for AXIAL JOINTG elements with coincident grids.
Check for missing CID2 for relevant JOINTG element types.
Info to list non-zero length JOINTG elements.

JOINTG Element Enhancements

New combination joint types: RPINROTA and CARTORIE.
DAMPING input for JOINTG property PJOINTG.
Check elems, Free 1-d’s enhanced to identify free JOINTG elements.

Thermal Analysis Enhancements

One Step Transient Thermal Stress Analysis for nonlinear static subcase.
New bulk card TEMPT.
ASSIGN card updates.

Enhancements

Updated Keywords

Added CONTF output request for linear static analysis.
Axial displacement as input for GAP elements in DRESP1 cards.
PLOADSF updated to assign element set.
DOPTPRM card updated with OPTIMOMP option.
SET entity updated with subtype as property for formula-based sets.
CFAILURE, CSTRESS and CSTRAIN output cards are updated with CORNER input in location option.
TLOAD1/TLOAD2 enhancements to reference Temp/TempD load as excitation load with excite type as TEMP.

General Enhancements

Solver option in export browser to export DMIG card in long format to retain the precision.
Tool tip description update for missing solver cards.
Solver option in export browser to export “Include file path relative to include statement.”

ASSIGN card truncated.
PRETENS load displays inconsistent graphics.
Performance improvement while reviewing subcase info in entity editor.
STRESS I/O card export issue.
