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.

General node update function implements pure virtual function defined in SpineMesh base class and performs specific node update actions: along vertical spines

Implements oomph::SpineMesh.

Reimplemented in oomph::BrethertonSpineMesh< ELEMENT, INTERFACE_ELEMENT >, and oomph::BrethertonSpineMesh< ELEMENT, SpineLineFluidInterfaceElement< ELEMENT > >.
