Thank you for the reply!

Actually I tried Batch mode, it stops in any case... in the .out file it shows that the following error occured:

There is at least 1 small equation solver pivot term (e.g., at the UX   
 degree of freedom of node 6778).  Please check for an insufficiently    
 constrained model.

Is it possible to force ansys to skip this error and proceed?
