Hi Claudia, 

My best guess is that the imported *.IGS geometry needs some clean up. There might be a discontinuity in the geometry like an open face/edge somewhere that the solver doesn't know what to do with, or maybe the parts haven't got all of their contact surfaces etc defined?  

Since you have Solidworks, you can try exporting the geometry in the Parasolid format, this is the *.x_T file type. Parasolid is generally more robust than *.IGS. and you can import that directly into the ANSYS Student product using either DesignModeler or SpaceClaim.  

Can you try that & report back. Also post some screenshots to help the community to get more context if the problem.
