Macro Definition Documentation

boundary_flux

#define boundary_flux	(		t,
			pe2
	)		(boundary_flux[2*(t)*(*polar_times_groups)+(pe2)])

Indexing macro for the angular fluxes for each polar angle and energy group for a given Track

fixed_sources

#define fixed_sources	(		r,
			e
	)		(fixed_sources[(r)*(*num_groups) + (e)])

Indexing scheme for fixed sources for each FSR and energy group

old_scalar_flux

#define old_scalar_flux	(		tid,
			e
	)		(old_scalar_flux[(tid)*(*num_groups) + (e)])

Indexing macro for the old scalar flux in each FSR and energy group

reduced_sources

#define reduced_sources	(		tid,
			e
	)		(reduced_sources[(tid)*(*num_groups) + (e)])

Indexing macro for the total source divided by the total cross-section, , in each FSR and energy group

scalar_flux

#define scalar_flux	(		tid,
			e
	)		(scalar_flux[(tid)*(*num_groups) + (e)])

Indexing macro for the scalar flux in each FSR and energy group

start_flux

#define start_flux	(		t,
			pe2
	)		(start_flux[2*(t)*(*polar_times_groups)+(pe2)])

Indexing macro for the starting angular fluxes for each polar angle and energy group for a given Track. These are copied to the boundary fluxes array at the beginning of each transport sweep

weights

#define weights	(		i,
			p
	)		(weights[(i)*(*num_polar_2) + (p)])

Indexing macro for the azimuthal and polar weights
