All degrees of freedom of grid points of two different grid sets of a model can now be equivalenced. The pairs of equivalenced grid points are not required to be adjacent to each other. The GMATCH Bulk Data Entry can be used to achieve such equivalence.
|
Thickness output via the THICKNESS I/O Options entry is now supported for composite elements referencing PCOMPP Bulk Data entries.
|
The 64-bit OptiStruct run can be activated using the –i64 run option. This feature avoids the 32-bit integer overflow in any OptiStruct module (Beta).
|
Duplicate element IDs between scalar elements (CELAS/CMASS/CDAMP) and other type of elements are now allowed. SYSSETTING,ELEMENTID is added for this purpose.
|
SYSSETTING,ADDMIDSIDE is added for this purpose.
|
Bar/Beam stress output is available for Transient Analysis.
|
Temperature field input for plate elements that allows specification of a temperature gradient through the shell thickness.
|
Supported for Sub-modeling (SUBMODEL) and Model Change (MODCHG).
|
ASSIGN,OP4DMIG is now available to read reduced matrices in the .op4 file.
|
The NEUBER option can now be used in conjunction with the SURF option on the STRESS and STRAIN entries.
|
PARAM,CURVSHL2,YES will activate this calculation.
|
This new option takes PTHRESH*maximum response value as threshold. This is available for ESE, STRESS and THERMAL output request.
|
Threshold option (TOP, RTOP, RTHRESH, and PTHRESH) has been added to Normal mode analysis and Modal Frequency Response/Modal Transient Analysis with MODAL output option.
|
Corner Strain is now available for Modal Frequency Response/Modal Transient Analysis with MODAL output option.
|
The results from global subcase can be saved and retrieved for local subcase job.
|
Fatigue Analysis can be included in Zooming (global-local) setup.
|
With new I/O options entry IDGLOBAL is added. This card allows to disable treating specific group of cards as part-localized. For example, IDGLOBAL,GRID will treat all GRIDS as existing in a global part, and they can be referenced on other cards only by numeric ID, instead of qualified ID.
|
The IDRF field on the RFORCE bulk data entry can be used to apply centrifugal force to a set of elements in a model. This allows the definition of different rotational forces to different parts of the model.
