Description: Parallel execution of element operations through MPI-based parallelization is available for static, implicit dynamic, or direct-solution steady-state dynamic analyses using substructures, if results recovery within substructures is not requested.

The boundary and surface impedances or nonreflective boundaries are supported for coupled acoustic-structural substructure generation analysis.

Other changes in the substructure generation procedure include the following:

• performance of substructure generation with multiple substructure load cases has been significantly improved, and

• writing substructure matrices to the output database (.odb) file is no longer supported.
