摘要

We have developed a highly parallel deterministic method for performing time-dependent particle (neutron, gamma-ray, or thermal radiation) transport calculations on arbitrarily connected 3-D tetrahedral meshes. The standard discrete-ordinates method, which is used to solve the first-order form of the transport equation, is extremely cumbersome to apply on such meshes and is based upon a mesh sweeping algorithm that is highly sequential in nature. A serial 1-D code for the CRAY-YMP and a parallel 1-D code for the CM-2 (Connection Machine) have been written to test our basic method. Comparisons between these two codes have shown that our new even/odd parity method is highly parallelizable. 10 refs., 2 figs.
