Public Member Functions
	RefineableFSISolidTractionElement (FiniteElement *const &element_pt, const int &face_index)
	Constructor: Create element as FSIWallElement (and thus, by inheritance, a GeomObject) with DIM-1 Lagrangian and DIM Eulerian coordinates. By default, we assume that the normal vector computed by the underlying FaceElement points into the fluid. If this is not the case, overwrite this with the access function FSISolidTractionElement::set_normal_pointing_out_of_fluid() Constructor for GeomObject is called explicitly because of virtual inheritance!

For instance, in a 1D FaceElement that is aligned with the Lagrangian coordinate line xi_0=const, only xi_1 will vary in the FaceElement.

void	resize_nodes (Vector< unsigned > &nadditional_data_values)
	Provide additional storage for a specified number of values at the nodes of the FaceElement. (This is needed, for instance, in free-surface elements, if the non-penetration condition is imposed by Lagrange multipliers whose values are only stored at the surface nodes but not in the interior of the bulk element). `nadditional_data_values`[n] specifies the number of additional values required at node `n` of the FaceElement. Note: Since this function is executed separately for each FaceElement, nodes that are common to multiple elements might be resized repeatedly. To avoid this, we only allow a single resize operation by comparing the number of values stored at each node to the number of values the node had when it was simply a member of the associated "bulk" element. There are cases where this will break! – e.g. if a node is common to two FaceElements which require additional storage for distinct quantities. Such cases need to be handled by "hand-crafted" face elements. More...

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...

void	fluid_load_vector (const unsigned &intpt, const Vector< double > &N, Vector< double > &load)
	Get FE Jacobian by systematic finite differencing w.r.t. nodal positition Data, internal and external Data and any load Data that is not included in the previous categories. This is a re-implementation of the generic FD routines with they key difference being that any updates of values are followed by a node update in the adjacent fluid elements since their position (and hence the shear stresses they exert onto the solid) may be indirectly affected by these. For greater efficiency this may be overloaded in derived classes, e.g. if it is known that for a specific FSIWallElement, the internal Data does not affect the nodal positions in adjacent fluid elements.

	Flag deciding if the Lagrangian coordinates of newly-created interior SolidNodes are to be determined by the father element's undeformed MacroElement representation (if it has one). Default: False as it means that, following a refinement an element is no longer in equilbrium (as the Lagrangian coordinate is determined differently from the Eulerian one). However, basing the Lagrangian coordinates on the undeformed MacroElement can be more stable numerically and for steady problems it's not a big deal either way as the difference between the two formulations only matters at finite resolution so we have no right to say that one is "more correct" than the other...

Detailed Description

class oomph::RefineableFSISolidTractionElement< ELEMENT, DIM >

////////////////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////////////////

RefineableSolidTractionElement "upgraded" to a FSIWallElement (and thus, by inheritance, a GeomObject), so it can be used in FSI. The element is templated by the bulk solid element and the spatial (Eulerian) dimension of the bulk element.

	)

Constructor: Create element as FSIWallElement (and thus, by inheritance, a GeomObject) with DIM-1 Lagrangian and DIM Eulerian coordinates. By default, we assume that the normal vector computed by the underlying FaceElement points into the fluid. If this is not the case, overwrite this with the access function FSISolidTractionElement::set_normal_pointing_out_of_fluid() Constructor for GeomObject is called explicitly because of virtual inheritance!
