A Note on Sets:

The FE Sets (e.g., FE Boundary and FE Region) created in nTop Platform can be made of up nodes, elements, edges, or faces, but only certain target formats support all of these. In general, the Abaqus .inp format is very robust and well-supported and even works well when translated into other tools including ANSYS Workbench using the "External Model" system. If applicable, this format is generally recommended when communicating FE data for mechanical applications.

 

*You can only export one FE Mesh at a time when exporting it with FE Sets.
