I would like to make a simple simulaion with NX11 - NX Nastran - SOL 101 with a beam, like on the picture:
I created a solution, but NX did`t solve it. It didn`t write about any errors, just "no results". I think the problem is in constraints, but I am not sure.
Could anybody check my .sim file or other files and explain me where I made a mistake?
Thanks in advance!
Solved! Go to Solution.
The model is statically indeterminate: the constraints are all located on the same planar face and are only applied in the direction normal to that face.
This only constrains 3 rigid body motions: translation normal to the face and rotations about the two in-plane axes. There are 3 unconstrained rigid body motions: the two in-plane translations and rotation about the plane normal.
You need to add more constraints. Easiest would be to change the simple support at one end to a fixed support.
