Importing NASTRAN bdf / Exporting ANSYS cdb - no elements

Recommended Posts



im looking to import a NASTRAN mesh into ANSYS.

This can be done directly in workbench, but a lot of information is lost.


Specifically I would like to maintain named selections / components - so my strategy was to bring the Nastran bdf into hypermesh, create my groups there, and then export as a cdb before importing it into workbench


The problem is whenever I export to cdb I only get nodes in the *.cdb, no elements.


I am using Hypermesh 14.0 - anyone have a workaround for this?


Thanks !
