| 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
////////////////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////////////////
Axisymmetric (one-dimensional) interface elements that allow the application of a volume constraint on the region bounded by these elements. The volume is computed by integrating x.n around the boundary of the domain and then dividing by three. The sign is chosen so that the volume will be positive when the elements surround a fluid domain.
These elements must be used together with the associated VolumeConstraintElement, which stores the value of the target volume.

Helper function to fill in contributions to residuals (remember that part of the residual is added by the the associated VolumeConstraintElement). This is specific for 1D line elements that bound 2D cartesian fluid elements.
/////////////////////////////////////////////////////////////////// ///////////////////////////////////////////////////////////////////
Helper function to fill in contributions to residuals (remember that part of the residual is added by the the associated VolumeConstraintElement). This is specific for axisymmetric line elements that bound 2D axisymmetric fluid elements. The only difference from the 1D case is the addition of the weighting factor in the integrand and division of the dot product by three.
Implements oomph::VolumeConstraintBoundingElement.
