3. NATURE OF PHYSICAL PROBLEM SOLVED

FEM-RZ is a computer program for solving multi-group neutron transport problems in two-dimensional cylindrical (r,z) geometry. It can solve not only eigenvalue problems but also other problems, such as fixed source problems.

[ top ]

4. METHOD OF SOLUTION

The method of higher order finite elements is used for the spatial variables. It is based on the discontinuous method with Galerkin-type scheme. The dicrete ordinate Sn method is used for the angular variables.

6. TYPICAL RUNNING TIME

A three-group, S4, 4X3 mesh point, second order approximation, K-eff calculation requires about 0.1 minutes of FACOM 230-75 time.
