Hey Foamers,

I'm running a simulation using the foamJob script to give me an output file and run the process in the background. The simulation end criteria will allow it to run for an extremely long amount of time (it is a transient simulation). How does one stop the foamJob script from running the process in the background prior to reaching the end criteria?

This is another somewhat related question as well (but may need to be posted as its own thread) - How does one extract the initial residual of the solved variables in a transient simulation with foamLog? foamLog only seems to post the final residual.

How about the various linux commands to kill a job, e.g. "kill -9 <pid>", or "killall <name>" or use "top", press k and enter the pid. If your controlDict is "runTimeModifiable" you could also change the endTime. Just try it out.

As far as I know foamLog is a bash script which utilizes awk to get the specific informations. A starting point would be to use a standard editor like "kate", "nedit" or "vi" and go through the script. Copy and paste the line where "final residual" is extracted and modify it.

Or even more confortable change the "stopAt" to "noWriteNow", "writeNow" or "writeNext" (see User Guide - "4.3 Time and data input/output control" for more information)

If you don't what to bother yourself to much, there is a great set of tools called pyFoam (http://www.openfoamwiki.net/index.php/Contrib_PyFoam). Easy to install and to use. It should bring you lots of the functions you are looking for. Have especially a look at "pyFoamPlotRunner.py"

Enjoy,
