Detailed Description

template<unsigned DIM>
class BidomainWithBathRhsMatrixAssembler< DIM >

BidomainWithBathRhsMatrixAssembler

This class only exists to construct a matrix, the matrix which is used to assemble the RHS in monodomain problems. Therefore, although it inherits from the assembler hierachy, it is not an assembler for any particular PDE problem, it is just used to assemble one matrix. Therefore only ConstructMatrixTerm is properly implemented.

The matrix that is constructed is in fact the mass matrix for a 2-unknown problem. ie ***IF*** the unknowns were ordered [V1 V2 .. V_N phi_e1 ... phi_eN ], the matrix would be [M 0] [0 0] where M_ij = integral over TISSUE elements phi_i phi_j dV, where phi_k is the k-th basis function

Todo:: #1063 make this class inherit from BidomainRhsMatrixAssembler

		c_vector< double, DIM > &	rPhi,
		ChastePoint< DIM > &	rX
	)			`[inline, virtual]`

The term arising from boundary conditions to be added to the element stiffness vector - except this class is only used fpr constructing a matrix so this is never called.

Parameters:

	rSurfaceElement	the element which is being considered.
	rPhi	The basis functions, rPhi(i) = phi_i, i=1..numBases
	rX	The point in space
