[petsc-users] KSP and SuperLu, Umfpack

[Sylvain Desroziers]

Hi,

I'm trying to use SuperLu and Umfpack LU solvers with Ksp. Using "-ksp_type
preonly -pc_type lu -pc_factor_mat_solver_package superlu [or umpfpack]",
there's no problem.

But I don't know how to configure ksp without command line options... How to
choose and switch external pâckage ?

Thanks,

Sylvain
