Products: Abaqus/Standard Abaqus/Explicit
Benefits: You can now translate CDH-style welds from a NASTRAN bulk data file to fasteners in Abaqus. You can also translate additional frequency-related elements in NASTRAN.
Description: The abaqus fromnastran execution procedure now includes the new parameter cdh_weld, which enables you to translate CHEXA elements with RBE3 elements at all eight corner nodes to fasteners in Abaqus. By default, CHEXA elements with RBE3 elements at all eight corner nodes are translated to the type of 8-node element specified in the chexa parameter. If cdh_weld=ON, CHEXA elements with RBE3 elements at all eight corner nodes are translated to fasteners in Abaqus.
In addition, Abaqus now supports the translation of FREQ3 and FREQ4 entities in NASTRAN to mode-based definitions of excitation frequencies for steady-state dynamic procedures in Abaqus.
