14.2.5 Add_to_Matrix_Equation_Ortho_Diffusion Procedure

The Add_to_Matrix_Equation_Ortho_Diffusion procedure adds the linearized version of the Ortho_Diffusion Term to the specified matrix equation. It currently assumes that there is a one-to-one correspondence between the Ortho_Diffusion locus (e.g. Cells) and the equation and variable numbering, and furthermore assumes that the locus is Cells.

Calling syntax:

call Add_to_Matrix_Equation (Diff_Term, ELLM, RHS_MV)

Input variables:

	Diff_Term		The Ortho_Diffusion Term to be added.
	ELLM		The ELL Matrix to be incremented.
	RHS_MV		The right-hand side Mathematic Vector to be incremented.

Output variables:

	ELLM		The ELL Matrix that has been incremented.
	RHS_MV		The right-hand side Mathematic Vector that has been incremented.

Internal variables:

	Matrix_Columns		Columns for the added matrix values.
	Matrix_Rows		Rows for the added matrix values.
	Matrix_Values		Calculated values to be added to the matrix or vector.
