3. NATURE OF PHYSICAL PROBLEM SOLVED

The transport equation in slab geometry is solved using the multigroup collision probability method. The collision probabilities are also calculated by this programme.

[ top ]

4. METHOD OF SOLUTION: Successive overrelaxation.

[ top ]

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Variable dimensioning techniques are used so that the only restriction on the size of the problem is the available core storage.

[ top ]

6. TYPICAL RUNNING TIME

It depends on the type of problem. Test case requires approximately five minutes.

[ top ]

7. UNUSUAL FEATURES OF THE PROGRAM

Solves eigenvalue or fixed source problems with periodic boundary conditions or condition of no incom- ing particles.
