Detailed Description

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

Simple implementation of AbstractFeObjectAssembler which provides mass matrices for a given mesh, multiplied by a scale factor if required. In other words, the matrix

M_{ij} = k integral_{domain} phi_i(x) phi_j(x) dV

where phi_i is the i-th (linear) basis function and k the scale factor (constant throughout the mesh).

Implemented ComputeMatrixTerm(), defined in AbstractFeObjectAssembler. 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.
