Hi everybody,

As I'm new on this Forum, I will present myself quickly. I' working in a german company as CFD engineer since 7 months. This two last months I tried to use OpenFOAM to make some HVAC simulations.

I made a simulation (with a mesh of 20 million cells) last week on parallel with 6 processors. But I deleted by mistake the constant/polymesh directory. I still have the polymesh directory on the 6 different processors. But now I'm not available (without this constant/polymesh files) to postprocess the calculation.

before I deleted it I allready made the reconstructPar -latestTime so I also got the results of my simulation for the latestTime.

Is it possible, with the data of the latestTime and the different processors directory to recreate the constant/polymesh files ?

Thank you for your help

Clement

Greetings Clement and welcome to the forum!

It should be as simple as running:

reconstructPar -constant

When in doubt you can always check other options given by OpenFOAM applications by running with "-help", e.g.:

reconstructPar -help

Good luck!

Thanks for your attention b........

........ but this way doesn't work :

FOAM Serious Error :
From function IOobject::readHeader(Istream&)
in file db/IOobject/IOobjectReadHeader.C at line 89
Reading "/home/daten/projects/audi/defrost_analysis/CFD/OpenFOAM_run_2_pw_test_2.0.x/constant/polyMesh/points" at line 0
First token could not be read or is not the keyword 'FoamFile'


It seems that by doing reconstructPar -constant OpenFOAM try to construct the mesh directly from the constant directory and not from the processors directory. This is not going to help me because I don't have the constant/polymesh anymore .......... another idea may be ??

Thanks

Clement

Did you run reconstructPar or reconstructParMesh? The second is the one you need.

Another option would be to use the native OpenFOAM reader for Paraview and do the postprocessing directly on an decomposed case.

Thank you (you two) really much,

that worked perfectly with

reconstructParMesh -constant

and then

reconstructPar -latestTime

You just saved my life .............
