Hi, I'm a quite expertise fem user and i've a problem that not meet before today.
I modelled some bolts and to simplify the model I have used CBUSH NASTRAN ELEMENTS.
the .f06 indicate that there are a mechanisms in X direction.
all the degree of freedom are locked because the cbush connect two RBE2 (123456) and the PBUSH has K=10e10 stifnes in 123456 direction.
What's happen?
Thanks to advance to everybody give me any suggest.
