HyperWorks 12.0 Release Notes

Enhanced Solution Control Entries
• RESVEC(NOAPPL): The NOAPPL option turns off residual vector generation due to loads. This
turns off both the UNITLOD and APPLOD residual vector generation.
Enhanced Bulk Data Entries
• CMSMETH: The ability to specify the solver to use (LAN for Lanczos and AMSES for AMSES) has
been added. In addition, the Lanczos SHFSCL and AMSES AMPFFACT parameters have been added.
• CMSMETH: Using the DMIGDV continuation of the CMSMETH data, the contents of an include file
used for optimization of the Super Element modal frequencies and their corresponding structural
viscous damping values is specified
• DRESP1: Added FRERP for defining equivalent radiated power as a response.
• PANELG: Generic panel definition for ERP or panel participation output.
• ERPPLN: Panel definition for equivalent radiated power output.
• TSTEP: Added W3 and W4 fields allowing these values to be defined differently for each set of time
increments.
• TSTEPNX: Added options to control small displacement assumption and fixed time points.
• SET: Added the TYPE RIGID to define sets of RIGID elements. These sets can be used on the
PFPATH data.
Resolved Issues
• The MPC and rigid element force contribution in GPFORCE output for frequency response could
be incorrect. Now correct contributions from MPC’s and rigid elements are output in the GPFORCE
results for frequency response.
• The MPCFORCE output for frequency response could be incorrect.
• Temperature dependent Structural Damping is now available. The T(GE) data on the MATT1,
MATT2, MATT3, MATT8, and MATT9 is now supported.
• Use of PARAM,LFREQ in modal transient analysis produced incorrect results. Now correct results are
obtained in modal transient analysis when PARAM,LFREQ is used.
• Modal transient analysis with enforced motion (SPCD) gave poor results. A new algorithm was
implemented for modal transient analysis with enforced motion (SPCD). Now the results match
those from direct transient analysis.
• Unless DISP(ROT)=ALL was requested, the GPKE values were wrong when AMLS or EIGRA was
used. This has been corrected.

Ply-based Composite Definition Can Now be Used in MBD Analysis
PCOMPP ply based composite property data can now be used in the Multi-body Dynamic analysis using
rigid bodies (PRBODY) and flexible bodies (PFBODY).
