Hello everyone, I have a question. I just start to work as a stress engineer and found something weird in CBUSH element. Sometimes it gives large forces (BUSH Fx, Fy and Fz) in a simple static analysis. Does it happen with somebody? May be someone knows explanation?
I work with FEMAP and NX NASTRAN.
Thanks in advanced.
