Hi nlgyro,
Thank you for the reply!
Unfortunately, after I posted the thread I found out in the "Advanced Nonlinear Theory and Modeling Guide" of Nx Nastran that with SOL 601 ESE doesn't work. In fact, not only this but also some other outputs (e.g. stress/strain for beam element) are not available with this simulation. I can imagine that it is a problem of communication between Nx Nastran and ADINA. Hopefully in the following versions an higher integration will be provided.
