When exporting a FEM model into the .INP format, I occasionally encountered the following two problems:
The loads are not exported at all (there is no *STEP / *ENDSTEP section in the INP file).
Although I select tetrahedral elements, the INP file may also contain: *ELEMENT,TYPE=C1D2.
One additional question
- Is it possible to define and export into .INP several load cases - this means that the .INP file has to contain several *STEP / *ENDSTEP sections?
