no solid body to pocess in cosmosXpress

I have the problem with cosmosexpress as today it tells methere is no solid body to process.
I've already madde a study on the same part, the only difference isI suppressed/deleted some features.
The message appears right at the beginning so I can do nothing. Doyou know what creates this problem?

Attached is the part I am struggling with.SolidworksSimulation
