对子模型法模型进行了优化，取全局模型中红框部分作为子模型，去除子模型之外区域，对子模型重新进行网格划分，使其网格更加规整细小，最后于切割边界处施加子模型边界条件（submodel boundary），提交作业（job），对夹杂物及其周边基体进行重新计算。

The submodel method model was optimized by taking the red box part of the global model as the submodel, removing the areas outside the submodel, and re meshing the submodel to make its mesh more regular and fine. Finally, submodel boundary conditions were applied at the cutting boundary, and the job was submitted to recalculate the inclusion and its surrounding matrix.
