Hi all:
I have recently purchased SW2011 and it's running great. I am running some thermal stress simulation in a wirebonding model. Since the linear analysis shows
the wire is passing the yield stress and the wire is encaped by slicione rubber, nonlinear thermal stress analysis is required.
In the linear analysis, I constrain the model by using the option" use soft spring to stabilize the model" but I cannot find the same opinion in the nonlinear interface.
Is there some similiar opinion to stabilize the model or there are some ways to constains the model with out introducing big stiffness matrix singularity?
Many thanks.
