化工仿真过程中，需要考略化学材料间反应后产生的复杂物理变化，这对于专业知识不够广泛的仿真工程师而言很头疼，但COMSOL内置了大量已知的化学反应式，可供直接调用，极大的简化了工程人员的工作量。(In the process of chemical simulation, it is necessary to examine the complex physical changes caused by the reaction between chemical materials, which is a headache for a wide range of simulation engineers, but COMSOL has a large number of known chemical reactions, Greatly simplifies the workload of engineering staff.)
