COMSOL Simulation Error: Failed to find a solution for all parameters

Please login with a confirmed email address before reporting spam

Hey Everyone, I am trying to simulate a model to perform the hysteretic analysis of Lithium Niobate. But I am constantly getting the same error, "Status: Error The following feature has encountered a problem: - Feature: Stationary Solver 1 (sol1/s1) **Failed to find a solution for all parameters, even when using the minimum parameter step. No convergence, even when using the minimum damping factor. Returned solution is not converged. Not all parameter steps returned. Total time: 112 s. Process status indicates that process failed. Process status indicates that process failed."** I have declared all the material parameters carefully and have also checked the "Auxiliary Sweep" (Study>Study Extensions>Auxiliary Sweep), I have tried different ranges of time, but nothing worked. Can anyone please help me with it... Thanks!!

The full details and causes of an error condition can only occasionally be understood by inspection of Comsol software-generated error message(s) in isolation. I encourage you to post your .mph file to the forum, so that it can be reviewed by others here, and so that the issue(s) in your particular model will be easier to identify.
