Enumeration Type Documentation

enum mfem::AssemblyLevel

strong

Enumeration defining the assembly level for bilinear and nonlinear form classes derived from Operator.

Enumerator
FULL	Fully assembled form, i.e. a global sparse matrix in MFEM, Hypre or PETSC format.
ELEMENT	Form assembled at element level, which computes and stores dense element matrices.
PARTIAL	Partially-assembled form, which computes and stores data only at quadrature points.
NONE	"Matrix-free" form that computes all of its action on-the-fly without any substantial storage.

Definition at line 30 of file bilinearform.hpp.

enum mfem::ElementDofOrdering

strong

Constants describing the possible orderings of the DOFs in one element.

Enumerator
NATIVE	Native ordering as defined by the FiniteElement. This ordering can be used by tensor-product elements when the interpolation from the DOFs to quadrature points does not use the tensor-product structure.
LEXICOGRAPHIC	Lexicographic ordering for tensor-product FiniteElements. This ordering can be used only with tensor-product elements.

Definition at line 65 of file fespace.hpp.

enum mfem::ErrorAction

Action to take when MFEM encounters an error.

Enumerator
MFEM_ERROR_ABORT	Abort execution using abort() or MPI_Abort(). This is the default error action when the build option MFEM_USE_EXCEPTIONS is set to NO.
MFEM_ERROR_THROW	Throw an ErrorException. Requires the build option MFEM_USE_EXCEPTIONS=YES in which case it is also the default error action.

Enumerator
SingleValued
DoubleValued

Definition at line 26 of file restriction.hpp.

Memory classes identify sets of memory types.
