simulation processing error

Hi,

I am trying to run to a simulation for a fairly large file, with a basic mesh.

When I try to run it, solidworks goes into not responding mode and the geometry preparation window is running forever(about 2 hours now). How do I proceed?

Computer specs are: Intel Xeon 3.00 GHz processor, 32 GB Ram, 5GB Nvidia Graphics Card.
