摘要
Geant4是一种应用广泛的蒙特卡罗程序包,其计算模型可以用几何描述标记语言(GDML)描述,然而依赖手工建模耗时且容易出错。本文提出一种基于计算机辅助设计(CAD)的Geant4自动建模方法,该方法能够把复杂的CAD几何模型自动转换为Geant4支持的GDML格式几何模型。基于多物理耦合自动建模软件平台MCAM进行了该方法的研究,通过包括聚变反应堆模型FDS-Ⅱ在内的测试例题的测试与校验,初步验证其正确性和有效性。
Geant4 is a widely used Monte Carlo transport simulation package. Its geometry models could be described in Geometry Description Markup Language （GDML）, but it is time-consuming and error-prone to describe the geometry models manually. This study implemented the conversion between computer-aided design （CAD） geometry models and GDML moldels. This method has been Studied based on Multi-Physics Coupling Analysis Modeling Program （MCAM）. The tests, including FDS-Ⅱ model, demonstrated its accuracy and feasibility.
