Hello,
I am currently working on the growth (or swelling) modeling of an isotropic hyperelastic material. After a certain strain, the growth leads to surface instabilities with various topologies depending on the material and initial conditions, and the folding parts, which located on the top boundary of the domain, start contacting each other. I wonder whether there is a built-in function in dolfin/dolfinx to account for the self-contact.
Thanks for all replies in advance.
