inlinevirtual

Implements mfem::Element.

Definition at line 59 of file triangle.hpp.

void mfem::Triangle::MarkEdge ( DenseMatrix & pmat )

virtual

Reorder the vertices so that the longest edge is from vertex 0 to vertex 0. If called it should be once from the mesh constructor, because the order may be used later for setting the edges.

Reimplemented from mfem::Element.

Definition at line 56 of file triangle.cpp.

void mfem::Triangle::MarkEdge	(	const DSTable &	v_to_v,
		const int *	length
	)

virtual

Mark the longest edge by assuming/changing the order of the vertices.

Reimplemented from mfem::Element.

Definition at line 101 of file triangle.cpp.

int mfem::Triangle::NeedRefinement	(	DSTable &	v_to_v,
		int *	middle
	)		const

virtual

Return 1 if the element needs refinement in order to get conforming mesh.

Reimplemented from mfem::Element.

Definition at line 38 of file triangle.cpp.

void mfem::Triangle::SetVertices ( const int * ind )

virtual

Set the vertices according to the given input.

Reimplemented from mfem::Element.
