Meshing errors! Unknown!

  • Im trying to perform a CFD analysis of a small UAV. I want to determine the CL and CD of the aircraft at zero AOA. I have taken the entire aircraft into the analysis (Not the half body). I have setup the mesh after following the tutorials. I am constantly getting an error, which Im not aware of.

MPI_ABORT was invoked on rank 19 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.

mpirun has exited due to process rank 28 with PID 207 on
node fbf6c9000b2f exiting improperly. There are two reasons this could occur:

  1. this process did not call “init” before exiting, but others in
    the job did. This can cause a job to hang indefinitely while it waits
    for all processes to call “init”. By rule, if one process calls “init”,
    then ALL processes must call “init” prior to termination.

  2. this process called “init”, but exited without calling “finalize”.
    By rule, all processes that call “init” MUST call “finalize” prior to
    exiting or it will be considered an “abnormal termination”
    This may have caused other processes in the application to be
    terminated by signals sent by mpirun (as reported here).

Hi @guc1997 !

Please share the project with us here so that we can have a look at it.
