Abstract

Hi,

I am performing a very simple cantilever analysis with 5 beam elements in Mentat. I get good results for deflection but Von Mises Stress is very small!! I was thinking that probably I need to connect the elements (rigid body?) or make nodal ties because the Moment Tensor is 0 in all 3 directions, but I don't know how to do it and I can't find an answer in the software documentation.

Can anybody help me?

Thanks
