我们提出了一个新版本的全三维光电离和尘埃辐射传输代码，MOCASSIN，它使用蒙特卡罗方法进行辐射传输。启用x射线的MOCASSIN允许对从无线电到伽马射线的辐射场强烈光电离的低密度气体环境进行完全几何无关的描述。该代码已经与文献中常规使用的其他已建立的代码进行了彻底的基准测试，使用简单的平面并行模型来测试标准条件下的性能。我们展示了基准测试的结果，并讨论了新代码的适用性和局限性，这应该对未来使用MOCASSIN进行天体物理研究具有指导意义。
We present a new version of the fully three-dimensional photoionization and dust radiative transfer code, MOCASSIN, that uses a Monte Carlo approach for the transfer of radiation. The X-ray enabled MOCASSIN allows a fully geometry-independent description of low-density gaseous environments strongly photoionized by a radiation field extending from radio to gamma rays. The code has been thoroughly benchmarked against other established codes routinely used in the literature, using simple plane-parallel models designed to test performance under standard conditions. We show the results of our benchmarking exercise and discuss the applicability and limitations of the new code, which should be of guidance for future astrophysical studies with MOCASSIN.
