Detailed Description

template<typename VectorType, typename MatrixType, typename SolverType>
class Utils::MGCoarseDirect< VectorType, MatrixType, SolverType >

This class implements the interface required by MGCoarseGridBase and allows a direct to be used as coarse grid solver in the Multigrid framework. The SolverType is provided as template parameter.

Note

Supported direct solver types are: SparseDirectUMFPACK and TrilinosWrappers::SolverDirect. Available vector types are the ones supported by the respective solve() (or vmult()) interfaces by such types. This means that SparseDirectUMFPACK supports only serial deal.II vectors, while TrilinosWrappers::SolverDirect supports as parallel vector types: LinearAlgebra::distributed::Vector and TrilinosWrappers::MPI::Vector.
