Detailed Description

template<unsigned DIM>
class oomph::UnsteadyHeatEquations< DIM >

A class for all isoparametric elements that solve the UnsteadyHeat equations.

\[ \frac{\partial^2 u}{\partial x_i^2}=\frac{\partial u}{\partial t}+f(t,x_j) \]

This contains the generic maths. Shape functions, geometric mapping etc. must get implemented in derived class. Note that this class assumes an isoparametric formulation, i.e. that the scalar unknown is interpolated using the same shape funcitons as the position.

Return the index at which the unknown value is stored.

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.
