CAD 模型与 Geant4几何模型双向自动转换方法研究

摘要

为实现Geant4几何模型与CAD模型的双向转换，以实现模型的快速建立、修改与高效迭代设计的迫切需求，本项目研究并实现了一种支持复杂CAD模型和Geant4几何模型双向自动转换的自动建模方法。本方法经过了大量例题的系统测试，并以Geant4典型测试例题液氩量热器模型为代表进行介绍。测试结果表明本文转换方法的正确性和有效性。%The bi-conversion of CAD model and Geant 4 geometry model was needed to meet the requirements of the quickly modeling , modify and effective iterative design .In this research , an automatic modeling method for bi-conversion between CAD model and Geant 4 geometry model was developed .This method was systemi-cally tested with abundance benchmark model , and introduces the result of Lar calorimeter test .The test result shows that the conversion method was correct and effective .
