OSTI ID:4069205
The solution of the neutron-diffusion equation in twodimensional triangular and hexagonal grids is discussed. Seven-point difference equatione in a triangular mesh are derived, and various methods of solving the resulting system of equations ars given. Included is an alternating direction-implicit method that was programmed for the IBM 704. The results of this method are compared with those obtained by using the FLEER code. A special code was also written to investigate the accuracy of the fourpoint difference equation. Results obtained with this code are presented. (auth)
