Constructor & Destructor Documentation

function DD2D	(	in	mesh,
		in	mat,
		in	quadrature
	)

Class constructor.

Set the mesh and material.

Parameters:

mesh	Problem mesh.
mat	Material definitions.

Returns:

Instance of the Equation class.

Member Function Documentation

function get_con_x	(	in	obj,
		in	octant
	)

function get_con_y	(	in	obj,
		in	octant
	)

function setup_angle	(	in	obj,
		in	mu,
		in	eta,
		in	xi
	)

Setup the equations for an angle.

Parameters:

mu	Cosine with respect to x axis.
eta	Cosine with respect to y axis.
xi	Cosine with respect to y axis.

function setup_group	(	in	obj,
		in	group
	)

Setup the equations for a group.

Here, we'll go through the grid and produce a fine mesh matrix of total cross-sections. This isn't the best thing for memory, but it cuts down a lot on the time within solve.

Parameters:

group

Current group.

function setup_octant	(	in	obj,
		in	octant
	)

Setup the equations for an octant.

Parameters:

octant

Current octant.

function solve	(	in	obj,
		in	g,
		in	psi_in,
		in	s,
		in	i,
		in	j,
		in	k
	)

Solve for the cell-center and outgoing edge fluxes.

Parameters:

g	Group index
psi_in	Incident flux vector, [horz=1, vert=2]
s	Cell source
i	Cell x index
j	Cell y index
k	Cell z index (NOT PRESENT)

Returns:

Cell center angular flux and outgoing edge fluxes.
