Hi,

Is there a way I can plot the residuals(real time) in OpenFoam as it is done in fluent or starcd /ccm.

Please let me know how, if it can be done.

Thanks

hi wolfgang,

I made the necessary changes to the residual file after downloading the file from the thread link that you had specified. But when I run the gnuplot Residuals
i get the following error
gnuplot: /home/research/OpenFOAM/ThirdParty-1.6/gcc-4.3.3/platforms/linux/lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by /usr/lib/libwx_baseu-2.8.so.0)

I think there is a problem with the gnuplot installation.

Is there way I can download the application and reinstall it.

Thank you.

Hi Subash,

yes you have to install gnuplot. Just serach for "gnuplot" in you software installation tool, e.g. Yast for Suse. It will be found.

Best regards

Hi,

install pyFoam "http://openfoamwiki.net/index.php/Contrib_PyFoam" and use pyFoamPlotWatcher

Hi Ullrich
I tried installing gnuplot- 4.4.0, but it still gives the same error as mentioned above. I have installed gnuplot-4.4.0 in the folder containing OpenFoam.

Hi christian,

I tried to install pyfoam0.5.3, I followed the instructions given in the link but it gives me the following error
Neither numpy nor Numeric python-package installed. Plotting won't work

is there any other file missing, let me know.

You'll have to install one of the two python libraries numpy (prefered) or Numeric. For most Linux-distros there exist packages in the package manager of those distros
