Hey, I ran into a problem with the interFoam solver. Whenever I remake (wmake) the solver after adding a couple of comments I get a warning saying: there is an 'unused variable' from the readPISOControls.H . So I copied the original interFoam solver and renamed it and ran wmake, and I get the same warning:

Is this just something I can ignore? Or is there something wrong with my interFoam solver? Thanks,

Hi Eelco,

it is just what it says: A warning about an unused variable. Nothing to worry about.

This happens if a variable is declared that is not used in the rest of the code.

Best regards

Hi Eelco,

nCorr is unused
I have exactly the same warnig message

Hi Florian,

Thanks, i was wondering which variables isn't used.

[feijooos]

isn't nCorr used in the PISO loop in interFoam.C?

// --- PISO loop
for (int corr=0; corr<nCorr; corr++)
{
#include "pEqn.H"
}

I also specify it in my fvSolution file.
