Single-layer spine mesh class derived from standard 2D mesh. The mesh contains a layer of spinified fluid elements (of type ELEMENT; e.g SpineElement<QCrouzeixRaviartElement<2>). It constructs the spines and contains the information on how to update the nodal positions within the mesh as a function of the spine lengths. Equations that determine the spine heights (even if they are pinned) must be specified externally or else there will be problems. More...

Detailed Description
template<class ELEMENT>
class oomph::SingleLayerSpineMesh< ELEMENT >
Single-layer spine mesh class derived from standard 2D mesh. The mesh contains a layer of spinified fluid elements (of type ELEMENT; e.g SpineElement<QCrouzeixRaviartElement<2>). It constructs the spines and contains the information on how to update the nodal positions within the mesh as a function of the spine lengths. Equations that determine the spine heights (even if they are pinned) must be specified externally or else there will be problems.

Constructor for spine 2D mesh: Pass number of elements in x-direction, number of elements in y-direction, axial length and height of layer, and pointer to timestepper (defaults to Static timestepper).
The mesh must be called with spinified elements and it constructs the spines and contains the information on how to update the nodal positions within the mesh as a function of the spine lengths. Equations that determine the spine heights (even if they are pinned) must be specified externally or else there will be problems.
