HyperWorks 12.0 Release Notes

Equivalent Plastic Strain
Equivalent plastic strain is available as a direct response for nonlinear response optimization using the
equivalent static load method. This is supported for NLGEOM, IMPDYN and EXPDYN subcase types.
Mechanical and Thermal Strains for Composites
In the past only total strain was supported as an internal response. Now, the total, mechanical only, or
thermal strain only can be used as responses.
Eigenvector
Components of the eigenvector are now available as internal responses. This allows matching and
targeting mode shapes.
Stress Constraints for a Cluster of Elements
Stress constraints for a cluster of elements can now be defined. This provides a way of removing
artificial stress concentrations from the formulation, which would otherwise have an influence on the
optimization solution.

12.0 Release Notes - Output
DVCREL Data
Optimized element data controlled by the DVCREL data are output to the .prop file.
Shape Variables with Heat Transfer Subcases
Shape design variables are output for optimization with heat transfer subcases so that analysis results
can be plotted on the updated shapes.
Design Property Output
OUTPUT,PROPERTY has been enhanced to support “ANY” and “DESIGN” as arguments.
OUTPUT,PROPERTY,ANY specifies that all properties should be output (including non-design properties),
while OUTPUT,PROPERTY,DESIGN specifies only designable properties be output.
“DESIGN” is the default behavior.
MINMAX/MAXMIN Reporting
Previously, the reported MINMAX/MAXMIN value was always the value of the first objective function
(whether it was retained or not), instead of being the actual minimum/maximum value. The output
has been enhanced by looping through the retained objectives and selecting the appropriate minimum/
maximum value.
Optimization History Output
The HyperGraph ASCII results file, .hgdata is now output for nonlinear response optimization.
