Detailed Description

template<unsigned DIM>
class ContinuumMechanicsNeumannBcsAssembler< DIM >

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.

void ContinuumMechanicsNeumannBcsAssembler< DIM >::AssembleOnBoundaryElement ( BoundaryElement< DIM-1, DIM > &  rElement,
c_vector< double, STENCIL_SIZE > &  rBElem,
unsigned  boundaryConditionIndex 
)
protected

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

Parameters
rElementThe element to assemble on.
rBElemThe 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.
boundaryConditionIndexinto the traction BCs structures in the problem definition
