Workflow for Importing Nastran Mesh Directly
I'm trying to import a Nastran file directly into Explicit Dynamics. I have read some other posts (https://forum.ansys.com/discussion/14809/i-need-help-please and https://forum.ansys.com/discussion/6685/importing-a-geometry-step-file-and-a-nastran-mesh-into-explicit-dynamics) and have been able to open the nastran file and run a simulation and get results.
However, when I use Explicit Dynamics or Mechanical, a new mesh of tetraheadral elements is generated and doesn't match the volume mesh of prism elements used in the nastran file.
In the past, I believe the Workbench toolbox included a Fine Element Modeler, but it is no longer available. Is there a workflow or tool I should use in order to be able to run a simulation with the original nastran mesh preserved?
