typedef L2_FECollection mfem::DG_FECollection

Declare an alternative name for L2_FECollection = DG_FECollection.

Definition at line 169 of file fe_coll.hpp.

Enumeration Type Documentation

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.

Performs a global L2 projection (through a HypreBoomerAMG solve) of flux from supplied discontinuous space into supplied smooth (continuous, or at least conforming) space, and computes the Lp norms of the differences between them on each element. This is one approach to handling conforming and non-conforming elements in parallel. Returns the total error estimate.
