You're not very specific, but it looks like you have a divergence in solving the equation for c.

Hi Bernhard, thanks,
I attached the solver with the case.Must only compile before run.
I tried different types of solvers, and different relaxation factors, but without success to converge.
If anyOne can look at, or even try ?

really, thanks a lot

Best Regards,
T.D.
