6-noded, quadratic, C0 continuous finite element in 2D space that defines a triangle.
The ordering of the nodes is counter clockwise. That is the nodes should be defined in the following order:
(0,1) 2 * |\ | \ | \ (0,0.5) 5 * * 4 (0.5, 0.5) | \ | \ *-----*-----* 0 3 1 (0,0) (0,0.5) (0,1)
This class defines the geometry of the FE problem. It must be combined with the physics component of the problem. This has already been done in the following classes:
