[OpenFOAM] Acquiring scalar names

tj22 · May 8, 2006, 13:55

As discussed before I am writing a reader for paraview which does not require installing OpenFOAM. I am looking through the files to obtain the names of the scalars for the timesteps while the names for timestep 0 are available in fvSolution, I cannot locate a file containing the names of all the scalars available in the other timesteps. There seem to be more scalars in those timesteps than in timestep 0.

So is there a file that contains these names? Or will I have to do a directory dump? (which will cause a problem of not being cross platform).

I'm afraid there is no such file (and it's even worse: you'll have to look into the files to determine whether they're vol-Fields or not)

It is really no problem to parse the header to determine vector, scalar, etc, it is however a problem to have no idea what files are avaible to parse.

I guess my only option is to call a system command to acquire the directory structure, that is going to be painful.

Look at usage of IOobjectList, e.g. in dataConversion/foamDataToFluent/foamDataToFluent.C

It will return you a list of all Foam files in a time directory. You can then use e.g. lookupClass to extract files of a certain type.

Actually the answer was to use vtkDirectory but thanks.
