Hey Foamers,
I'm having some trouble in working with rnTimePostProcessing, in order to create some images.


I found this guide, but not more other explanation:https://www.openfoam.com/documentati...ocessing-usage


The main problem is that mine installation (OpenFoam 7) gives me:


Caught FatalError
--> FOAM FATAL ERROR:

Unknown function type runTimePostProcessing



I attach here the controlDict file:
/*--------------------------------*- C++ -*----------------------------------*\

Hi Carlo,

think you need to compile this utility:

run ./Allwmake in
.../src/functionObjects/graphics/runTimePostProcessing/

Best regards,
Za-ck

Hey Za-ck,
thanks for your answer...but where I can find that file?
I mean, if you look in that folder, there isn't the graphics subfolder.
https://github.com/OpenFOAM/OpenFOAM...unctionObjects


Is that folder link to a specific version? OpenFOAM1906?
Thanks a lot,
Carlo

Hello Carlo,


I don't think this functionObject is implemented in the foundation version. It has been initially released in ESI's OpenFOAM v3.0+ version (release notes here) and has been improved in the newer versions (see v1906 release notes)


So you will probably need to use ESI's branch to use it. Or maybe try to compile it in your own version but I don't know if it's straightforward or not.



Regards,
Yann

Thanks Yann.
I checked in Esi's openFOAM and I found the code:
https://develop.openfoam.com/Develop...unctionObjects


I have to check how to install now ESI's OpenFOAM. I mean, openFoam 7 is more simple to install.


Thanks,
Carlo
