Is there an "easy" way to define self-contact?

[kptarun403]

Hi, I am trying to do self-contact simulation, could u please give me the input file.

Self-contact when contact regions are unknown (Abaqus-like general contact)

I’m trying to run a self-contact simulation in CalculiX for a highly complex deforming shape. In the initial phase I cannot predict which regions will come into contact, so I’m trying the “single contact skin” approach. Based on a YouTube comment and the related Discourse thread (“Is there an easy way to define self-contact?”), I created only one *SURFACE and used the same surface as both master and slave: *CONTACT PAIR, INTERACTION=self, TYPE=NODE TO SURFACE, ADJUST=0.1 Sselfcontact, Sselfco…
