Cad Import For Monk And Mcbend By Converting To Tetrahedral Mesh Format

摘要

Reactor components (e.g. fuel assemblies) and other equipment (e.g. transport flasks) are designed using Computer Aided Design (CAD) packages. It is useful to be able to directly use these geometries in Monte Carlo calculations; Monte Carlo tracking using these geometries requires processing of complex surfaces which may slow the calculation. Here we describe a simplified approach of converting the CAD file into an Ansys ASCII-format tetrahedral mesh, and importing this into the ANSWERS codes MONK[1] and MCBEND[2].
