Updated FORTRAN-77 Version of the 2-D Static Neutron Transport Code DIAMANT2 for Regular Triangular Geometry

摘要

This report describes a major revision of the DIAMANT2 code, which evolved from the DIAMANT-code. DIAMANT2 solves the static multigroup neutron transport equation in planar geometry using the S/sub N/-method. Spatial discretization is accomplished by taking finite differences on a meshgrid composed of equilateral triangles. This new version of DIAMANT2 is written in FORTRAN 77 and designed to run on scalar and vector computers. This report contains a detailed documentation of the program and the input description as well as some experiences gained with the code on several vector computers. (ERA citation 13:000759)
