Edge¶

class dolfin.cpp.mesh.Edge(*args)¶

Bases: dolfin.cpp.mesh.MeshEntity

An Edge is a MeshEntity of topological dimension 1.

Create edge from mesh entity

Parameters:	& entity (MeshEntity) – (`MeshEntity` ) The mesh entity to create an edge from.

dot()¶

Compute dot product between edge and other edge

UnitSquare mesh(2, 2);
Edge edge1(mesh, 0);
Edge edge2(mesh, 1);
info("%g", edge1.dot(edge2));

Parameters:	Edge & edge (const) – (`Edge` ) Another edge.
Return type:	double
Returns:	double The dot product.

length()¶

Compute Euclidean length of edge

UnitSquare mesh(2, 2);
Edge edge(mesh, 0);
info("%g", edge.length());

Return type:	double
Returns:	double Euclidean length of edge.
