OpenFOAM - Quick way to delete previous calculation & HowTo get access to variables

Hi!

Is there a quick way to delete all previous timesteps in a calculation (e.g. a script, deleting all directories regarding the time-steps w/o the "0" directory)?

plus: how can I tell the solver which variables to write to the result file - using buoyantBoussinesqPisoFoam I would like to have access to e.g. k and eps for post-processing.

Regards,
Kriz

Hi Kriz,

Just install pyFoam, a great set of python utilities by Bernhard Gschaider for doing all kind of openfoam tasks. Have a look at
http://openfoamwiki.net/index.php/Contrib_PyFoam

For clearing your case directory, it would become one single command:

pyFoamClearCase.pl .

Regards,

Eelco

There might be a script in OpenFOAM-1.6/bin (only had a quick glance and nothing caught my fancy)

It's not an uncommon task. I usually use http://openfoamwiki.net/index.php/Co...amClearCase.py for that (but usually every computer I touch becomes polluted with that stuff, so this is the easiest thing to do for ME, not necessarily for everyone)

That was discussed last week (I think the discussion was about rho) and two functionObjects that do that were referenced

Just curious: are you sure you're using a turbulence model that HAS k/epsilon (because usually such a turbulence model writes these out)

There is a command included in OpenFOAM that lists all of the time directories, you just just have to type > foamListTimes.

Now, if you want to remove all those directories, you type > foamListTimes -rm

Code:

mv 0 O

rm -r 0*

rm -r 1*

rm -r 2*

rm -r 3*

rm -r 4*

rm -r 5*

rm -r 6*

rm -r 7*

rm -r 8*

rm -r 9*

mv O 0

rm -r postProcessing

Or shorter

Code:

rm -r 0.* [1-9]*

removes all time folders but zero.

Which can be problematic for some of the tutorial-cases that have a 0.orig-directory

Hey guys,

if you need, it is possible to use the command "foamCleanTutorials".
It is very usefull command to clean the directory.

Thanks it worked on OpenFoam version 2012 as well.

But it also will remove the mesh-related files, (which are in constant/polymesh/ directory)
So you have to again do the meshing stuff (i.e.- blockMesh).
Basically, the foamCleanTutorial command makes your case's folder contain only the 0/, constant/, system/ directories. (and maybe someother files), more like a fresh case folder.

This is useful when the time files are reconstructed, but when the time files are in decomposed processors use this is good :

rm -rf processor*/[time]
or
rm -rf processor*
to delete all processors

For decomposed cases, you can also use foamListTimes with the processor option:

Code:

foamListTimes -processor -rm
