Detailed Description

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM, unsigned PROBLEM_DIM>
class AbstractFeSurfaceIntegralAssembler< ELEMENT_DIM, SPACE_DIM, PROBLEM_DIM >

Similar to AbstractFeVolumeIntegralAssembler but is used for constructing finite element objects that are based on SURFACE INTEGRALS, as opposed to volume integrals.

This class assumes that the concrete class only needs to assemble a vector, not a matrix. (Can be extended in the future if needed).

Hence, the (effectively) pure method, that needs to be implemented, is ComputeVectorSurfaceTerm().

The surface terms is assumed to come from Neumann BCs, so only the surface elements containing non-zero Neumann BCs (from the BoundaryConditionsContainer given) are assembled on.

The interface is the same the volume assemblers.

Calculate the contribution of a single surface element with Neumann boundary condition to the linear system.

Parameters

rSurfaceElement	The element to assemble on.
rBSurfElem	The element's contribution to the RHS vector is returned in this vector of length n, the no. of nodes in this element. There is no need to zero this vector before calling.

Returns: the vector to be added to full vector for a given Gauss point in BoundaryElement, ie, essentially the INTEGRAND in the boundary integral part of the definition of the vector. The arguments are the bases, x and current solution computed at the Gauss point.

** This method needs to be overloaded in the concrete class **

Parameters

rSurfaceElement	the element which is being considered.
rPhi	The basis functions, rPhi(i) = phi_i, i=1..numBases
rX	The point in space
