Detailed Description

A class for all isoparametric elements that solve the Foeppl von Karman equations.

\[ \nabla^4 w - \eta Diamond^4(w,\phi) = p(x,y) \]

and

\[ \nabla^4 \phi + \frac{1}{2} Diamond^4(w,w) = 0 \]

This contains the generic maths. Shape functions, geometric mapping etc. must get implemented in derived class.
