Dear All,
I have modified step-22 to solve system of Maxwell's equations, and then
used step-40(and 55) to parallelize the code.
In the serial version I used
template<int inner_solver_id>
struct InnerPreconditioner;
template<>
struct InnerPreconditioner<0>
{
typedef SparseDirectUMFPACK<double> type;
};
template<>
struct InnerPreconditioner<1>
{
// type of preconditioner for an iterative solver
};
Which defined the type of preconditioner I need for CG solver, in order to
obtain yet another preconditioner for FGMRES solution of my system.
Now with parallel implementation I would like to use
PETScWrappers::SparseDirectMUMPS instead of SparseDirectUMFPACK.
However I am getting the following error:
error: ‘SparseDirectMUMPS’ in namespace ‘LA’ does not name a type
typedef LA::SparseDirectMUMPS type;
Here LA is defined as
namespace LA
{
#if defined(DEAL_II_WITH_PETSC) && !(defined(DEAL_II_WITH_TRILINOS) &&
defined(FORCE_USE_OF_TRILINOS))
using namespace dealii::LinearAlgebraPETSc;
# define USE_PETSC_LA
#elif defined(DEAL_II_WITH_TRILINOS)
using namespace dealii::LinearAlgebraTrilinos;
#else
# error DEAL_II_WITH_PETSC or DEAL_II_WITH_TRILINOS required
#endif
}
Is it possible to do something similar to step-22 with SparseDirectMUMPS,
or I have to rewrite the code and remove the struct InnerPreconditioner ?
Thank you very much in advance for all your help.
Anna
