Problems solved! You need to make sure you have admistrator rights all the time with these processes!
In case you haven't learned this by now, the "f" means that the part is "fixed" in the assembly. The "-" means it is "floating". As you discovered, it shouldn't have anything to do with whether or not the part imports successfully into your FEA program.
I have an assembly of two parts, and one of them successfully imports into the abaqus via the Solidworks-Abaqus Associative interface link, however the other one is "skipped" according to the Abaqus process report.
The only difference I can see between the two parts in the Solidworks assembly, is that the one that exports to abaqus has a " (f) " for the part name in the part tree and the one does not export successfully has a " ( - ) " in the part name. I am not sure what this means and I would appreciate on how I can get around this problem, I wanted to avoid importing the same part again as I have used on of the parts to perform a boolean cut of the other part, so wanted to avoid moving or replacing this part.
