I am using the MUMPS to solve a nonlinear variational problem:
mysolver.parameters("newton_solver")["linear_solver"] = "mumps";
mysolver.solve();
and I got the following error:
Solving nonlinear variational problem.
Newton iteration 0: r (abs) = -nan (tol = 1.000e-10) r (rel) = -nan (tol = 1.000e-09)
