3. NATURE OF PHYSICAL PROBLEM SOLVED

The steady-state, multigroup, two-dimensional neutron diffusion equations are solved in x-y, r-z, and r-theta geometry.
top ]
4. METHOD OF SOLUTION

A Gauss-Seidel type of solution with inner and outer iterations is used. The source is held constant during the inner iterations.

14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS

ANY OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS.
The auxiliary routine POTLUK generates a flux and adjoint guess for  a VARI-QUIR problem whose internal region boundaries are different from those of a previous problem using the flux and adjoint from that problem. This enables users to vary the interfaces at will and  still optimize running time. VARI-QUIR III requires a double interpolation subroutine.
