Hello, I am new to Comsol and I am trying so simulate the follwing:
A piece of hyperalstic material is placed on top of a rigid body. The hyperelastic materials is then deformed under the gravitational force. I have made a simulation and it works sometimes, for parameters which do not cause a large deformation. However, when increasing for example the mass, Comsol canot find a solution anymore; the error is: No convergence, relative step size too small.
Thanks for your help, Mahsa
