Detailed Description

////////////////////////////////////////////////////////////////////////// ////////////////////////////////////////////////////////////////////////// ////////////////////////////////////////////////////////////////////////// This is a base class for all SolidFiniteElements that participate in FSI computations. These elements provide interfaces and generic funcionality for the two additional roles that SolidFiniteElements play in FSI problems:

They parameterise the domain boundary for the fluid domain. To allow them to play this role, FSIWallElements are derived from the SolidFiniteElement and the GeomObject class, indicating that the every specific FSIWallElement must implement the pure virtual function GeomObject::position(...) which should compute the position vector to a point in the SolidFiniteElement, parametrised by its local coordinates.
In FSI problems fluid exerts a traction onto the wall and this traction must be added to any other load terms (such as an external pressure acting on an elastic pipe) that are already applied to the SolidFiniteElements by other means.

The fluid-traction on the SolidFiniteElements depends on the fluid variables (velocities and pressures) in those fluid elements that are adjacent to the SolidFiniteElements' Gauss points. In an FSI problem these velocities and pressures are unknowns in the overall problem and the dependency of the SolidFiniteElement's residual vector on these unknowns must be taken into account when computing the element's Jacobian matrix.

For each Gauss point in the FSIWallElement, we therefore store:

[a] pointer[s] to the FSIFluidElement[s] that is [are] "adjacent" to the Gauss point in the FSIWallElement.
the vector[s] of the local coordinates (in the fluid element[s]) that identify the point in the fluid element that is (deemed to be) "opposite" that Gauss point. (Note that we do not require the discretisations of the fluid and solid domains to match exactly, therefore, small "gaps" may occur between fluid and solid elements.)

By default, each FSIWallElement is assumed to be exposed to fluid loading only on one of its faces. For elements that are immersed into fluid, so that a fluid traction is "exerted from both sides", the element can store pointers to multiple adjacent fluid elements (and local coordindates in these). This capability must be enabled by a call to FSIWallElement::enable_fluid_loading_on_both_sides().

Since the fluid traction can involve derivatives of the velocity (think of Newtonian fluids), the traction is also affected by changes in the nodal positions of the adjacent fluid elements. Since fluid and solid discretisations are not required to match, the nodal positions in an adjacent fluid element can be affected by the positional variables in another FSIWallElement. To capture this influence, we provide the function FSIWallElement::node_update_adjacent_fluid_elements() which does exactly what it says....

Finally, since oomph-lib's fluid and solid elements tend to employ different non-dimensionalisations for the stresses, the fluid traction (computed by the adjacent fluid element, on the fluid stress-scale) may have to be scaled by the ratio \( Q \) of the stresses used to non-dimensionalise the two sets of stresses. For instance, for a fluid stress non-dimensionalisation based on the viscous scale \( \mu U / L\) (as in oomph-lib's Navier-Stokes elements) and a non-dimensionalisation of the solid mechanics stresses, based on a Young's modulus \( E \), as in oomph-lib's KirchhoffLoveBeamElements, the stress ratio is given by

\[ Q=\frac{\mu U}{LE} \]

For other wall/fluid element combinations the definition of \( Q \) will differ – check the documentation and/or implementation to see which parameters are used to non-dimensionalise the stresses in the respective elements!

The function FSIWallElement::fluid_load_vector(...) computes the fluid traction on the wall on the wall stress-scale. This function may be called in the get_load (say) function of a specific FSIWallElement to add the fluid load to the other tractions that may already be applied to the element by other means. By default a stress-ratio of \( Q = 1 \) is used but this may be overwritten with the access function FSIWallElement::q_pt().

◆ fluid_load_vector()

void oomph::FSIWallElement::fluid_load_vector	(	const unsigned &	intpt,

	)

protected

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. Get the contribution to the load vector provided by the adjacent fluid element: Pass number of integration point in solid element, and the unit normal vector (pointing into the fluid!) and return the load vector. Note that the load is non-dimensionalised on the wall-stress scale, i.e. it is obtained by computing the traction (on the fluid stress-scale) from the adjacent fluid element and then multiplying it by the stress-scale-ratio \( Q. \).

Get the contribution to the load vector provided by the adjacent fluid element: Pass number of integration point in solid element, and the unit normal vector (pointing into the fluid on the "front" of the FSIWallElement) and return the load vector. Note that the load is non-dimensionalised on the wall-stress scale, i.e. it is obtained by computing the traction (on the fluid stress-scale) from the adjacent fluid element and then multiplying it by the stress-scale-ratio \( Q. \). If element is loaded on both sides, the fluid load computed from the reverse element is subtracted, because it's computed with the same normal vector.
