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.
