What does these error messgae mean?

Hi,

When I solve a nonlinear, coulped model in paramteric solver, the following message apperas:

Error:
Failed to find a solution for the initial parameter:
No convergence, even when using the minimum damping factor.
Returned solution has not converged.


Would you like to guide me how should I do in the next step?


Thank you very much!!

For me it always happened when I put non physical conditions. Try to proof read your initial conditions and www.comsol.com/support/knowledgebase/905/

Hi

it can also come from initial conditions that are too far away from the default "0", so sometimes ramping some large values, or just setting more realistic initial conditions might help.

But certanly, one should always recheck all BC with this message

Good luck
