Class Documentation

template<int dim, int spacedim = dim>
class ImportedFiniteElementFields

A reusable collection of frozen finite-element fields imported from VTK.

The target triangulation is supplied by the owning Problem and must already describe the same mesh as the VTK file. The object owns the imported DoFHandler, finite element, catalog, and distributed coefficients, while its field views share those coefficients without copying them.

Public Types

using VectorType = ImmersXLA::MPI::Vector

using TriangulationType = dealii::parallel::TriangulationBase<dim, spacedim>

using DoFHandlerType = dealii::DoFHandler<dim, spacedim>

using SpaceView = FESpaceView<dim, spacedim>

using FieldType = Field<dim, spacedim, dealii::FEValuesExtractors::Scalar>

Public Functions

ImportedFiniteElementFields(const std::string &vtk_filename, const TriangulationType &triangulation, MPI_Comm communicator = MPI_COMM_WORLD)

Import all VTK fields onto an already prepared Problem triangulation.
