| Set the "master" volume constraint element The setup here is a bit more complicated than one might expect because if an internal pressure on a boundary is hijacked in TaylorHood elements then that the "traded" value may already be stored as nodal data in this element. This causes no problems apart from when running with PARANOID in which case the resulting repeated local equation numbers are spotted and an error is thrown. The check is a finite amount of work and so can be avoided if the boolean flag check_nodal_data is set to false. More... | |

Detailed Description
template<class ELEMENT>
class oomph::SpineSurfaceVolumeConstraintBoundingElement< ELEMENT >
////////////////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////////////////
The Two-dimensional interface elements that allow the application of a volume constraint specialised for the case when the nodal positions of the bulk elements are adjusted using spines. To enforce that a fluid volume has a certain volume, attach these elements to all faces of the (3D Cartesian) bulk fluid elements (of type ELEMENT) that bound that region and then specify the "pressure" value that is traded for the constraint.
