Hi everybody!

I am working on a model representing a structure with LAMINATE sections. As there are DLOADs acting on it, I need to run it with NLGEOM=yes, so that the deformed new position of the structure is taken into account while the loads are acting on it. The problem is, although it runs ok in the NLGEOM=NO, with NLGEOM=YES, it does not converge. I cheked the model, and does not seem to be anything wrong (It run ok without NLGEOm!) This happens even with a simple flat surface model with DLOADs on it. What could be wrong? Is there any incompatibility among NLGEOM and LAMINATE properties?

Thank you all....

There should not be any such relation
Just check material's plastic properties once again.
By the the way what is the error message for divergence
