Hi All,
I encounter a convergence problem in my COMSOL model. It is greatly appreciated if someone help me to solve this problem.
As you can see in the attached model, I am modelling a cartilage using poroelasticity module. A total load of 1.4[MPa] is applied in one second ramp on top of the cartilage.
I need to solve this model using "large deformation" formulation so I checked "include geometric nonlinearity" in the study setting. But the model cannot converge. However I can solve the model with "include geometric nonlinearity" unchecked, but I need to solve it under large deformation formulation.
Your help is greatly appreciated!
Many thanks in advance.
Regards,
Saeed
