Hi everyone, 

 

I am dealing with a Problem at Postprocessing I cannot handle. My stress pot looks weird (image attached). 

I am using QUAD8-elements and I apply a single force one one side an a clamp on the other side ( cantilever modell with a changed geometry) with a quasi-static Loadcase.

Can anybody help?

 

Thanks in advance!!

 

regards

Peter

    Try choosing an average method and contour it again
