Hey,

 I got some problem with my model. I want to create a contact area between a sphere and a quader just like in the example 'nlstat.hm'. I defined the sphere as slave and the quader as master and the rest of steps i did it also as describe but after my simulation i became this error: 

 *** ERROR #  941 ***
 NON-CONVERGENT NONLINEAR ITERATIONS FOR SUBCASE         1

 Suggestions:
 * Large nonlinear errors indicate that the model may have insufficient support
   - check the data (ideally the model should be stable without gap elements).
   Or try stabilized version of expert system: PARAM,EXPERTNL,CNTSTB.

 

Can someone please help me to solve this error?

Thx
