Dear Femap users,
A simple question. I perform a non linear analysis with gap element. This element is subject to an axial tensile force, but I don't understand why the Gap axial force results is negative.
Gap axial forcePlease, can anyone clarify me this point?
Go to Solution.
The Nastran documentation lists that a positive force shows compression. See number 5 in the CGAP bulk data entry of the Nastran Quick Reference Guide.
Here's a model showing one GAP element in tension and one in compression.
