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 Geant4 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 Geant4 geometry model was developed. This method was systemically 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.
