virtual void disable_ALE ()
 This is an empty function that establishes a uniform interface for all (derived) elements that involve time-derivatives. Such elements are/should be implemented in ALE form to allow mesh motions. The additional expense associated with the computation of the mesh velocities is, of course, superfluous if the elements are used in problems in which the mesh is stationary. This function should therefore be overloaded in all derived elements that are formulated in ALE form to suppress the computation of the mesh velocities. The user disables the ALE functionality at his/her own risk! If the mesh does move after all, then the results will be wrong. Here we simply issue a warning message stating that the empty function has been called. More...

Member Function Documentation

template<class TAYLOR_HOOD_ELEMENT >
Vector<std::pair<Data*,unsigned> > oomph::ProjectableGeneralisedNewtonianTaylorHoodElement< TAYLOR_HOOD_ELEMENT >::data_values_of_field ( const unsigned &  fld)
inlinevirtual

Specify the values associated with field fld. The information is returned in a vector of pairs which comprise the Data object and the value within it, that correspond to field fld. In the underlying Taylor Hood elements the fld-th velocities are stored at the fld-th value of the nodes; the pressures (the dim-th field) are the dim-th values at the vertex nodes etc.

Implements oomph::ProjectableElementBase.
