Detailed Description

template<class ELEMENT>
class BrethertonElement< ELEMENT >

"Bretherton element" is a fluid element (of type ELEMENT) for which the (inflow) velocity at those nodes that are located on a specified Mesh boundary is prescribed by Dirichlet boundary conditions. The key is that prescribed velocity profile can be a function of some external Data – this dependency must be taken into account when computing the element's Jacobian matrix.

This element type is useful, for instance, in the Bretherton problem, where the parabolic "inflow" profile is a function of the film thickness (represented by Spine heights) at the "outflow".
