The 3DHZETRN code, with improved neutron and light ion (Z≤2) transport procedures, was recently developed and compared to Monte Carlo (MC) simulations using simplified spherical geometries. It was shown that 3DHZETRN agrees with the MC codes to the extent they agree with each other. In the present report, the 3DHZETRN code is extended to enable analysis in general combinatorial geometry. A more complex shielding structure with internal parts surrounding a tissue sphere is considered and compared against MC simulations. It is shown that even in the more complex geometry, 3DHZETRN agrees well with the MC codes and maintains a high degree of computational efficiency.
最近开发了 3DHZETRN 代码，其中改进了中子和轻离子（Z≤2）的输运程序，并使用简化的球形几何形状与蒙特卡罗（MC）模拟进行了比较。结果表明，3DHZETRN 在与 MC 代码一致的程度上与它们彼此一致。在本报告中，将 3DHZETRN 代码扩展为能够在一般组合几何形状中进行分析。考虑了一种具有包围组织球体的内部部件的更复杂的屏蔽结构，并与 MC 模拟进行了比较。结果表明，即使在更复杂的几何形状中，3DHZETRN 与 MC 代码也非常吻合，并保持了高度的计算效率。
