Reply To: Implicit – Force contacts on initial time step

[Nicolas Fontaine]

I am trying to reproduce this simulation, only the folding and the pleating part (so without the stent, the metallic frame):

The folding part is fine, the problem is for the pleating part, the non-linear solver does not find equilibrium. I guess there is a problem with my contacts or the implicit parameters.

I also followed this document to help me with the implicit analysis but without more success so far:
