Detailed Description

3-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:

(0,1) 2

|\ | \ | \ | \ | \ | \ *---—* 0 1 (0,0) (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:
