how is the solution for a bolt pre-load approached/implemented in Nastran?
I read there are different approaches on different sites regarding bolt pre-load in general and used with other software:
"Pretension can generally be modeled with temperature, constraint equations, or initial strains."
What is used for Nastran if I apply a bolt pre-load to an 1D-Element or a cut-plane?
Where can I read more about it?
The above link describes how to apply the preload in Simcenter.
