Description

The adaptive correction algorithm (AWLM-WLD-scheme) for the 4-th order nodal LM-scheme for the transport equation is presented. This method provides for the positivity of solution, eliminate rough errors of approximation with coarse meshes and thus is convenient for solution of deep penetration radiation problems. Calculation results of neutron and photon transport in two-dimensional shielding compositions show that the AWLM-WLD scheme ensures multifold computational gain in the running time and memory in comparison with the Sn-method. The AWLM-WLD scheme is realized in the ROZ-6.4 program for one-dimensional geometries and in the KASKAD-1 program for two-dimensional ones. 10 refs.; 6 figs.; 1 tab
