2024年12月2日 · In NECP-MCX V1.0, the Constructive Solid Geometry (CSG) is used, which can handle complex geometries theoretically. However, plenty of human effect is needed to build large complex geometries in engineering applications.

building a hybrid CSG-UM model was developed in NECP-MCX V2.0. The CSG model and the UM model are built separately by the user and then the UM model is inserted into the CSG model. In particle tracking, the UM is predominant over the CSG, which means that the users do not need to treat the boundary between the CSG and the UM carefully.

2025年2月22日 · We analyzed the type of CSG representation most favorable for improving the efficiency of Monte Carlo particle tracking. With this goal, we designed a BRep-to-CSG conversion algorithm for the CMGC. For convenience of use, it supports parallel model conversion and provides a graphical user interface for setting the materials and other parameters.
