Sliding Mesh 不能进行并行计算
-
感谢东岳大神回复。
transonicMRFDyMFoam我用它来计算一个叶轮的Stage,如果用rhoPimpleDymFoam的话,第二个solver是否支持MRF呢?如果不支持MRF我怕用DyM的时候,不用设定转子内流体本身的转动。
不知道在这种情况下rhoPimpleDyMFoam是否适用?如果在超算上运行,log 如下:

曾经我的电脑也可以做出这个错误,后来就不知道怎么也做不出这个错误来了。
电脑安装的是Ubuntu 16.04系统。非常感谢!

没有什么区别,ggi
是foam-extend
的名字,AMI
是OpenFOAM
的名字。
