hi,
i finish the calculation of my case(i can see the process of calculation in the terminal window),now i have to output all the time-steps of the calculation.
what can i do?

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,
thank you very much.i will have a try!

hi，
i can not output the process of the calculation.i am use OF1.4.1.is there another way to solve problem?

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 want to output the residuals or the convergency of the calculation.but i can not fix it from your advice.could you describe in detail?
thank you very much!

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.

hi Wolfgang Heydlauff sir

i am solving NACA 0012 Airfoil case in simple foam solver....can anybody tell me how wil u know that the solution is converged or not..

[wolle1982]

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..!

hi

I AM USING OPENFOAM 1.4.1...
