Definition at line 25 of file tetrahedron.hpp.

int mfem::Tetrahedron::refinement_flag

protected

The refinement flag keeps (in order) :

Two marked edges given with local index (0..5) for the two faces that don't have the refinement edge as edge. The refinement edge is determined by the first two nodes of the tetrahedron. Each marked edge is stored in 3 bits (or as implemented in the functions CreateRefinementFlag and ParseRefinementFlag.
Type of the element, stored in the next 3 bits.
The rest is free for now.
