Thanks again for your advice! I'm quite sure about setting the mesh orientation :). As you said, I tried to mesh with CQUAD4. There were some warnings but the solution was done. But stil I had to think about putting on CQUAD8, which better represent the geometry. I'm not very sure...

Thank you very much for your reply. You´re right, I´m doing this FEM with NX6 Advanced Simulation. The material directions should be parallel to the tube axis. I´m using shell elements CQUAD8. I tried the last tip you suggested, but without any succes. Maybe also wrong material...
Does anybody know, how to define material orientation for laminated tube in NX6? I´ve already done similar analysis for plate and I was succesful. I know, how to change material orientation using a vector or a coordinate system, but it seems, that the solver has a problem with the two remaining...
