Abstract

Abstract

Large equipment models need tremendous amount of three-dimensional solid entities to build, when using CSG method. For example, Dayawan reactor whole core model has tens of thousands of solid entities. A large-scale visual modeling software JLAMT for Monte-Carlo particle transport calculation is developed by the Institute of Applied Physics and Computational Mathematics (IAPCM). In this paper, for the particle transport program oriented visual modeling, a program module for hierarchical modeling and management is developed and plugged in JLAMT, which allows users to separate a complex model into different layers and edit part of the model in a certain layer. Therefore, it improves the performance and efficiency of three-dimensional modeling of complex models for the Monte Carlo particle transport calculation.
