Failed to find a solution for the initial parameter. Multigrid canceled. Returned solution is not converged.

Hello everyone,

I'm having a problem in my simulation, where it does not converge and return me this menssage when I cancel the simulation.
"Failed to find a solution for the initial parameter.
Multigrid canceled.
Returned solution is not converged.
"
What do I have to do to fix it?

Thanks

Gustavo
