solve()

void geosx::PetscSolver::solve	(	PetscMatrix &	mat,
		PetscVector &	sol,
		PetscVector &	rhs,
		DofManager const *const	dofManager = nullptr
	)

Solve system with an iterative solver.

Parameters

[in,out]	mat	the matrix
[in,out]	sol	the solution
[in,out]	rhs	the right-hand side
	dofManager	the Degree-of-Freedom manager associated with matrix

Solve Ax=b with A an PetscMatrix, x and b PetscVector.
