Detailed Description

template<unsigned DIM>
class BidomainMassMatrixAssembler< DIM >

Constructs a matrix with the mass matrix in the voltage-voltage block.

Ie. IF the bidomain unknowns were ordered [V1,..,Vn,phie_1,..,phie_n], the matrix would be, in block form

[ M 0 ] [ 0 0 ]

where M is the standard nxn mass matrix.

Since the bidomain ordering is not [V1,..,Vn,phie_1,..,phie_n] but [V1,phie1,..,Vn,phie_n], the matrix has a different form.

WORKS FOR BATH PROBLEMS AS WELL AS NON-BATH PROBLEMS (sets zeros in the voltage-voltage block for bath nodes, ie [ M 0 0 0 ] [ 0 0 0 0 ] [ 0 0 0 0 ] [ 0 0 0 0 ] where the ordering is Vtissue, Vbath, phi_tissue, phi_bath

ComputeMatrixTerm()

This method is called by AssembleOnElement() and tells the assembler the contribution to add to the element stiffness matrix.

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
