Detailed Description

template<class ELEMENT>
class oomph::TwoLayerSpineMesh< ELEMENT >

Two-layer spine mesh class derived from standard 2D mesh. The mesh contains two layers of spinified fluid elements (of type ELEMENT; e.g SpineElement<QCrouzeixRaviartElement<2>).

This mesh paritions the elements into those above and below a notional interface and relabels boundaries so that the mesh is as follows

| | 4 | | 2

| 6 |

| | 5 | | 1

| |

0 Update information for the nodes in response to changes in spine length is given, but additional equations must be specified in order to completely specify the problem.
