The typecast to HYPRE_Solver returns the internal amg_precond.
Implements mfem::HypreSolver.
|
inline |
| void mfem::HypreBoomerAMG::SetSystemsOptions | ( | int | dim | ) |
More robust options for systems, such as elastisity. Note that BoomerAMG assumes Ordering::byVDIM in the finite element space used to generate the matrix A.
