Parallel running error (high performance computer)
 
Hi Guys,
I am trying to use high performance computer for my case.
I am using MRFSimpleFoam, 5.5 million cells, 36 processors.
The case is running without any problem in my machine with 4 processors.
The same case I tryied to run many times in HPC but no success.
I tried different type of mesh as well, always its giving the error message as follows.
(I am struggling with this problem for last 3 days)

any help and suggestions are appreciated

Create time

Create mesh for time = 0
