Re: COMSOL Error Message

Thank you sir

I modified the program to run. I also have a error message following

"Repeated error test failures. May have reached a singularity.
Time : 6.331016568333548e-009
Undefined value found.
Undefined value found in the stiffness matrix.
There are 2 equations giving NaN/Inf in the matrix rows for the variable mod1.wAr_1p.
at coordinates: (2.3612e-005,9.08325e-005), (2.15237e-005,8.63755e-005), ...
and similarly for the degrees of freedom, NaN/Inf in the matrix columns.
Last time step is not converged.
- Feature: Time Dependent (Sol1/st1)
- Error Repeated error test failures. May have reache a singularity"

Would you mind to help me?
