I have a model that includes two parts solid and shell.
I've joined these two parts with merge nodes.
I want to do a linear static analysis on them.
After analysis, deformations are very small(0.3e-7).But in some places in the model, these two parts go inside or go apart.
While this does not happen, if I do a non-linear analysis on the same model with the same characteristics.
Is this a real deformation?
