CAD-Based Neutronics
A suite of computer codes and nuclear data library is being utilized to perform neutronic analyses for ARIES, ITER, FNSF and other US fusion studies:
- CUBIT is a solid modeling and mesh generation software toolkit developed and released by Sandia National Laboratories. It offers the ability to create and prepare the 3-D model needed for the CAD-based radiation transport analysis, assign materials and densities to all components, define boundary conditions, and tally the results
- The DAGMC (Directly Accelerated Geometry Monte Carlo) code is a software tool developed by the UW Computational Nuclear Engineering Research Group (CNERG) to perform Monte Carlo radiation transport on complex 3-D geometries created by solid modeling software. DAGMC converts any complex 3-D geometry into a faceted geometry of tetrahedrons and couples it to the radiation transport code MCNP5 and its FENDL continuous pointwise cross section data library. Performing radiation transport using a model created and prepared by CUBIT requires that the user create only a portion of the data cards associated with a typical MCNP input file.
