If you are using OpenFOAM-1.5
You can execute inside your case dir foamJob icoFoam The solver runs in background with the log file generated in your case dir. Hope this helps. |

You can also use a command line as follows:
icoFoam > log and then use tail -f log to have a look in real-time |

hi,
what exactly do you want to output? in realtime or in a log file. if you have written to a logfile (icoFoam >log) you can afterwards extract the log-file date with the command foamLog [logfilename] if you mean the residuals or the convergency of the calculation i use the "forces" tool (see other thread) and let the file plot in gnuplot. there you can easily see in realtime how convergent your calculation is. for this, it doesn't matter wheather you're interested in the forces afterwards or not. |

hi,
i see. since your using OF 1.4.1 you'll have to use the liftdragTool (see other thread) cause there is no forces-function in OF 1.4.1 yet. |

output the forces of a patch with forces-function (search forum) and plot with gnuplot "on-the-fly". if forces don't change, solution is converged.
. . don't call me "sir" again..! |
