immortality is on a distinguished road
I have set
Code:
writeCompression on;
and stop the run.now it gives an error:
Code:
Create time

Create mesh for time = 4e-06

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.

mpirun has exited due to process rank 0 with PID 3414 on
node Ehsan-com exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).

[Ehsan-com:03412] 2 more processes have sent help message help-mpi-api.txt / mpi-abort
[Ehsan-com:03412] Set MCA parameter "orte_base_help_aggregate" to 0 to see all help / error messages
Killing PID 3408
 PyFoam WARNING on line 232 of file /usr/local/lib/python2.7/dist-packages/PyFoam/Execution/FoamThread.py : Process 3408 was already dead
how can overcome this issue without decompressing individual files.

Hi Ehsan,

Does either one of the following files exist?
Code:
/home/ehsan/Desktop/Central/Turbulent_WR/low-Re/turbulent_lR700*50/processor0/4e-06/p
/home/ehsan/Desktop/Central/Turbulent_WR/low-Re/turbulent_lR700*50/processor0/4e-06/p.gz
If neither one of them exist, then it's possible that you stopped the simulation at a bad point in time, exactly when the solver was writing the fields and you made it stop.

The safe way to stop a running case is to edit the file "system/controlDict" and change the "stopAt" control to either "writeNow" or "nextWrite", which will ensure that the time snapshot is properly saved before ending. For more information: http://www.openfoam.org/docs/user/controlDict.php

Best regards,
Bruno
