Hello everyone,

I have been using openFoam 2.3 on a Linux OS (kubuntu) for a while now and i have already run successfully some cases.
Lately i tried installing the windows version of openFoam at my personal computer (windows 7 ultimate). Although the installation was completed without problem it doesn't run old cases i made when working on Linux OS.
Even when running the tutorial icoFoam/cavity from the linux OS on the windows platform i get the error:

-⁠-⁠> FOAM FATAL IO ERROR:
keyword pFinal is undefined in dictionary "C:/OpenFOAM/Kostas-3.0.x/run/cavity/system/fvSolution.solvers"

file: C:/OpenFOAM/Kostas-3.0.x/run/cavity/system/fvSolution.solvers from line 22 to line 33.

From function dictionary::subDict(const word& keyword) const
in file db/⁠dictionary/⁠dictionary.C at line 648.

FOAM exiting

that's because on openFoam 2.3.1 (Linux OS) you didn't have to define pFinal on the fvSolution file while on the other hand on openFOam for windows you have.

the windows version is 3.0 while the Linux is 2.3.1, but there should be compatibility going from 2.3.1 to 3.0 since it is an older version.
is there not compatibility between these two ?

thanks in advance

Quick answer: The problem has to do with how OpenFOAM changed between versions 2.3 to 3.0. The solution is to take a look at the same tutorial case on OpenFOAM 3.0 that you used from OpenFOAM 2.3.

Have a look here: https://github.com/OpenFOAM/OpenFOAM...tem/fvSolution - see the new block? This one:

    pFinal
    {
        $p;
        relTol          0;
    }
