I don't understand why my SOR (relaxation) diverge for a Laplacian resolution in finite diference scheme. If anyone could help me, I can send you my code (F77). Thanks Davoche

Thanks, but I don't think the SOR core is false.

In fact, I think the pb is link to my discretisation or stencil coefficient for the discretized Laplacian operator.
