hi everyone,
i tried to run the tutorial example of openFoam 3.0.x but i got this error.

--> FOAM FATAL IO ERROR: 
keyword pFinal is undefined in dictionary "/home/mohen/OpenFOAM/mohen-3.0.x/run/tutorials/incompressible/icoFoam/cavity/system/fvSolution.solvers"

file: /home/mohen/OpenFOAM/mohen-3.0.x/run/tutorials/incompressible/icoFoam/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

any idea whats wrong?? i searched throw the fvsolution script but i didn't see any pFinal there. i also copied the cavity tutorial from other versions but nothing changed

thanks all

Hi,

cavity tutorial is meant to be run with icoFoam, yet it seems you are trying to run PISO/PIMPLE family solver. As of commit a2e25d5, icoFoam runs smoothly in cavity tutorial.

Hi
I followed exactly the commands in the openfoam website, i'm sure i entered icoFoam to solve.

Hi,

You are right, I should have recompiled icoFoam with newly checked out source. As a workaround for the problem, you can change this part of fvSolution:

    p
    {
        solver          PCG;
        preconditioner  DIC;
        tolerance       1e-06;
        relTol          0;
    }

and make it

    "p.*"
    {
        solver          PCG;
        preconditioner  DIC;
        tolerance       1e-06;
        relTol          0;
    }

(so PCG linear solver is used for p and pFinal). Also you can report broken tutorial case in Mantis (http://openfoam.org/mantisbt).

Hi
thanks for your useful reply. I have another question. is there a problem with icoFoam in this version? or this error was just for the cavity tutorial?

Thanks

Hi,

I think all icoFoam tutorials became broken after commit 21cbbf7. I.e. after this source modification:

commit 21cbbf7beb561ce13a67790ce4c36a1371b17cd0
Author: Henry Weller <http://cfd.direct>
Date:   Thu Jan 28 09:03:51 2016 +0000

    pisoControl: Corrected handling of final inner (PISO) iteration control
...
+inline bool Foam::pisoControl::finalInnerIter() const
+{
+    return
+       corrPISO_ == nCorrPISO_
+    && corrNonOrtho_ == nNonOrthCorr_ + 1;
+}

fvSolution files in all icoFoam tutorials have to be modified ("p.*" instead of p, as I have written in previous post).
