Detailed Description

Abstract class for assembling surface-integral parts of vectors in continuum mechanics problems.

For such problems, the matrix has the form [A B1] [B2^T C ] (where often B1=B2 and C=0) and the vector has the form [b1] [b2]

This class adds surface integral components, arising from natural Neumann boundary conditions, to the spatial part of the RHS vector, ie to b1.

Calculate the contribution of a single element to the linear system.

Parameters

rElement	The element to assemble on.
rBElem	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.
boundaryConditionIndex	into the traction BCs structures in the problem definition
