[Libmesh-users] Normalization for nonlinear solver

[Renato P. <re...@gm...>]

Hi all,

I have a system of equations which differ by orders of magnitudes.
They are solved with PETSc SNES, and I am facing converging issues.

Do you know of any facility in libmesh/PETSc to normalize/precondition
these equations? I can, of course, do that manually... is that the way to
go?

Thanks
Renato
