Detailed Description

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
class StiffnessMatrixAssembler< ELEMENT_DIM, SPACE_DIM >

Simple implementation of AbstractFeVolumeIntegralAssembler which provides the stiffness matrix

K_{ij} = integral_{domain} grad phi_i(x) . grad phi_j(x) dV

where phi_i is the i-th (linear) basis function.

Implemented ComputeMatrixTerm(), defined in AbstractFeVolumeIntegralAssembler. See documentation in that class.

Parameters:

rPhi	The basis functions, rPhi(i) = phi_i, i=1..numBases.
rGradPhi	Basis gradients, rGradPhi(i,j) = d(phi_j)/d(X_i).
rX	The point in space.
rU	The unknown as a vector, u(i) = u_i.
rGradU	The gradient of the unknown as a matrix, rGradU(i,j) = d(u_i)/d(X_j).
pElement	Pointer to the element.
