foam-extend-4.0 求解器fsiFoam，并行方法是scotch，decomposePar -cellDist 操作出现如下问题。跪求大佬解答！附上两个log文件。
log.decomposePar log.decomposePar.solid

@李东岳 李老师您好！首先感谢您的回复。我在fe-40的tutorial中找到pisoFoam的算例——cavity。执行decomposePar依旧存在上述问题。无论是用scotch还是simple均会存在上述问题。目前我是在dyfluid下载的虚拟机上运行的。

然而如果不进行reconstructPar，在paraview在case type 为 Decomposed Case 时则显示内容如图2所示。用单核跑的结果仍为图2所示。
李老师请多指教！！！
