Our project aims to update the modelling of dust and molecular hydrogen within simulated galaxies. We will achieve this through the coupling of thermodynamic and chemical solvers in order to better model the rate at which dust populations grow and are destroyed. Furthermore, we add molecular hydrogen into the chemical network which allows us to explicitly calculate its abundance, rather than the approximate methods used before. This work will be done in collaboration with the SIMBA simulation project, and our new modelling procedures will be added to next-generation simulations within the group as standard. In doing this work we create a self-consistent and physically motivated model of dust and molecular hydrogen within the interstellar medium of simulated galaxies.

我们的项目旨在更新模拟星系中尘埃和分子氢的模型。我们将通过热力学和化学解算器的耦合来实现这一点，以便更好地对尘埃种群增长和销毁的速度进行建模。此外，我们将分子氢加入到化学网络中，使我们能够显式地计算其丰度，而不是以前使用的近似方法。这项工作将与SIMBA模拟项目合作完成，我们的新建模程序将作为标准添加到集团内的下一代模拟中。在这项工作中，我们在模拟星系的星际介质中创建了一个自洽的、物理激励的尘埃和分子氢模型。
