rhoPimpleFoam计算飞机跑几步就发散
-
各位大佬，我参考文献 3rd High-Lift Workshop Summary Paper - OpenFOAM, STAR-CCM+ & LAVA simulations on Unstructured Grids链接https://arc.aiaa.org/doi/10.2514/6.2018-1253。用rhoPimpleFoam计算飞机，但是算了几步就发散了，希望各位大佬帮忙看看是fvSchemes和fvSolution的问题嘛，还是nut、nuTilda设置的问题。
目前用的是作者上传到会议网站的网格，按照文章里说的，采用的是SA模型，以及动量和湍流项采用的是二阶迎风。
