I see. I cannot evaluate your model myself, i get the error
Nonlinear solver did not converge.
In segregated group 1:
Time : 10.02836128938059
Segregated group 1
Undefined value found.
Undefined value found in the stiffness matrix.
For mesh-case 1 there are 316 equations giving NaN/Inf in the matrix rows for the variable mod1.E10.
and similarly for the degrees of freedom, NaN/Inf in the matrix columns.
Last time step is not converged.
