turing off the log file?

bunni · April 21, 2010, 13:56

Sorry if this is a silly question, but how do I turn off the log file? Is there a command line toggle for that? I'm doing very long runs, and the log file gets into the Gb range, which is a little much. Cheers.

Control-C will kill the log file if it's already started. You can run a solver without the log file if you don't need the log. Instead of <foamJob simpleFoam>, just enter <simpleFoam> on the command line (or <mpirun -np x simpleFoam -parallel> if you're using more than one processor. The residuals will be displayed in your terminal window. I hope this helps,

Thanks, I was actually looking to toggle it off, as opposed to redirecting to stout. I didn't know about control-C, but I don't know if that will work on the job submission system. At the moment, I redirect to /dev/null. I also just used the <simpleFoam>, as you suggest.

I think your system is the only correct one, running simpleFoam 2>&1 > /dev/null
