Hi All,
I was trying to run the airfoil flow field simulation in parallel using Cluster. I decompose the domain into 4 and run it using simpleFoam with 4 processors. Then I get the following Errors: COLOR="Red"]Create time Create mesh for time = 0 Reading field p Reading field U Reading/calculating face flux field phi Selecting incompressible transport model Newtonian -------------------------------------------------------------------------- MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD with errorcode 1. NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes. You may or may not see output from other processes, depending on exactly when Open MPI kills them.[/COLOR] -------------------------------------------------------------------------- But the exactly same case, can be run successfully in serial and even in parallel with 4 processors in my own laptop. But when i submit this job into Cluster, it said the error. And i also checked the decompose.log file, the domain was decomposed successfully. The above error is read from the case.log file. Thanks in advance for your time!! Any guide will be helpful. |

This is the entire case.log file:

You are looking at the stdout and it doesn't show the actual error. Your cluster should generate a stderr file with you should read, that will have the fault in it.
