A new geometry capability has been implemented in MCNP that permits the existence of an unstructured mesh with its legacy Constructive Solid Geometry (CSG) capability to form a hybrid geometry. This new feature enables the user to build complex 3-D models with Computer Aided Engineering (CAE) tools, such as Abaqus, and perform a neutronics analysis on the same geometry mesh that is used for thermo-mechanical analyses. This paper will present an overview of the issues and problems encountered in implementing the requirements for the hybrid geometry capability in MCNP.
