3. DESCRIPTION OF PROGRAM OR FUNCTION

CAFDATS is a converter of angular fluxes of the DORT, ANISN and TORT systems. It works similarly to the TORSED or TORSET program in the DOORS code systems, and is designed to calculate the boundary source for the ANISN and DORT codes from the calculated fluxes by the DORT or TORT code.

4. METHODS

CAFDATS is designed to calculate the boundary source for the ANISN and DORT codes from the calculated fluxes by DORT or TORT.
There are five sub-programs in the program package:
- TXTODR converts calculated fluxes in the Cartesian geometry (X, Y, Z) of TORT code to the boundary source in the cylindrical geometry (R, Z) of DORT code,
- TRTODR converts calculated fluxes in the cylindrical geometry (R, Theta, Z) of TORT code to the boundary source in the cylindrical geometry (R, Z) of DORT code,
- TRTOAR converts calculated fluxes in the cylindrical geometry (R, Theta, Z) of TORT code to the boundary source in the infinite cylindrical geometry (R) of ANISN code,
- TXTOAX converts calculated fluxes in the Cartesian geometry (X, Y, Z) by TORT code to the boundary source in the infinite plane geometry (X) of ANISN code,
- DRTODR converts calculated fluxes in the cylindrical geometry (R, Z) by DORT code to the boundary source in the cylindrical geometry (R, Z) of DORT code.  
The angular fluxes for the boundary source of the secondary calculation are linearly interpolated from the nearest-neighbor angular fluxes in the angular and spatial meshes of the primary calculation.
