Inp file export and physical groups
Hi,
when an element is part of multiple physical groups it is exported once for every group, thus a lot of duplicates are created.
I suggest to export the whole mesh first (with sets for all entities: nodes -> NALL, elements -> EALL) and write the sets (physical groups) after the the mesh data. Here, the ELSET and NSET options should be used. See abaqus manual or calculix manual for the correct syntax of the ELSET and NSET commands. This should be easy to implement and will prevent multiple object definitions.
Thanks for your efforts! br Jakob
