Definition at line 250 of file qspace.hpp.

◆ GetFaceType()

FaceType mfem::FaceQuadratureSpace::GetFaceType ( ) const

inline

Returns the face type (boundary or interior).

Definition at line 240 of file qspace.hpp.

◆ GetGeometry()

Geometry::Type mfem::FaceQuadratureSpace::GetGeometry ( int idx ) const
