Detailed Description

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

\[ \nabla^4 w - \eta \frac{\partial}{\partial x_{\beta}} \left( \sigma^{\alpha \beta} \frac{\partial w}{\partial x_{\alpha}} \right) = p(x,y) \]

and

\[ \frac{\sigma^{\alpha \beta}}{\partial x_{\beta}} = \tau_\alpha \]

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

By default, these are: 0: w 1: laplacian w 2: u_x 3: u_y In derived multi-physics elements, this function should be overloaded to reflect the chosen storage scheme. Note that these equations require that the unknown is always stored at the same index at each node.
