PRELIMINARY STUDY ON APPLYING DISCRETE ORDINATES CODE SUPPORTING UNSTRUCTURED TETRAHEDRAL MESH TO THE 40-DEGREE TOROIDAL SEGMENT ITER MODEL

摘要

The discrete ordinates code under development by KAERI uses an unstructured tetrahedral mesh, and can thus be applied to solve the radiation transport in a complicated geometry. In addition, the geometry modeling process has become much easier because computational tetrahedral meshes are generated based on the CAD file by Gmsh. This program has been enhancing its performance and adding functions for each application.
