twoPhaseEulerFoam并行出错
-
最近在用twoPhaseEulerFoam求解案例,先用简单几何测试了边界条件的设置,网格如下,左右分别为进出口边界。并行求解50s并未出现任何错误。
但是在换用几何之后,使用mpirun -np 4 twoPhaseEulerFoam -parallel
命令运行之后无法并行,出现如下报错:[1] #0 Foam::error::printStack(Foam::Ostream&)[2] #0 Foam::error::printStack(Foam::Ostream&)[0] #0 Foam::error::printStack(Foam::Ostream&) at ??:?

局部网格如图所示:
固相堆积情况如下所示:(此处最大体积分数超过了限制最大体积分数0.62)
目前不知道为何并行出现错误,以及运行之后为何出现报错。
具体参数设置见附件:case.zip -
后续:
换用reactingTwoPhaseEulerFoam
后使用mpirun -np 4 reactingTwoPhaseEulerFoam -parallel
命令运行依旧报错(第一个报错似乎和CPU分配有关),目前使用mpirun reactingTwoPhaseEulerFoam
命令进行求解,运行测试案例之后发现与twoPhaseEulerFoam
结果有一些差别,具体模型还没仔细研究。
之前案例设置库朗数为5是否太大了,目前改为1,但是求解太慢了。[0] #0 Foam::error::printStack(Foam::Ostream&)[2] #0 Foam::error::printStack(Foam::Ostream&)[1] #0 Foam::error::printStack(Foam::Ostream&) at ??:?
