Detailed Description

Class to encapsulate all element-type specific methods.

For example, there would be one GenericElementType for tets, another for hexes, another for 10-node tets, etc.

Terminology: Natural Coordinates are a subset of the unit cube that can be mappped onto the element. The Shape Function at a given location lists the weights for each node used to interpolate values. The Jacobian lists the partials of real coordinates with respect to natural coordinates.
