4-noded, linear, C0 continuous finite element in 2D space.
The ordering of the nodes is counter clockwise. That is the nodes should be defined in the following order:
3 (0,1) 2 (1,1) *------------------------* | | | | | | | | | | | | *------------------------* 0 (0,0) 1 (0,1)
This is an abstract class. Specific concrete implemenations of this It must be combined with the physics component of the problem. This has already been done in the following classes:
