Hi foamers, i can't run my case in simplefoam because I have received the following message:

--> FOAM FATAL IO ERROR:
keyword SIMPLE is undefined in dictionary "/home/tesisti/OpenFOAM/tesisti-2.3.1/run/Pignatelli/pitching_airfoil/system/fvSolution"

file: /home/tesisti/OpenFOAM/tesisti-2.3.1/run/Pignatelli/pitching_airfoil/system/fvSolution from line 22 to line 97.

And I have this in my fvsolution:

Do you have any idea of what i have to modify?

[karoltomek]

You do not have at least one bracket (k is not closed)

k
{
solver smoothSolver;
smoother GaussSeidel;
tolerance 1e-8;
relTol 0.1;
nSweeps 1;
}

Check carefully your brackets.

[bullmut]

SIMPLE is also missing a "}"
karoltomek is spot on. double check your brackets

thanks so much i have already corrected this embarassing error

Hey, greetings,

I have something similar problem, I guess. So it says the following:

keyword wallDist is undefined in dictionary "/.../Ras/damBreak/system/fvSchemes"

file: /.../Ras/damBreak/system/fvSchemes from line 20 to line 53.

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

I tried to change from k-epsilon turbulance model to k-omega one at the case of damBreak and then it gave the error message above.

Here is the fvSchemes file what it contains:

ddtSchemes
{
default Euler;
}

gradSchemes
{
default Gauss linear;
}

divSchemes
{
div(rho*phi,U) Gauss linear;
div(phi,alpha) Gauss vanLeer;
div(phirb,alpha) Gauss interfaceCompression;
div(phi,k) Gauss upwind;
div(phi,omega) Gauss upwind;
div(phi,R) Gauss upwind;
div(R) Gauss linear;
div(phi,nuTilda) Gauss upwind;
div((nuEff*dev(T(grad(U))))) Gauss linear;
}

laplacianSchemes
{
default Gauss linear corrected;
}

interpolationSchemes
{
default linear;
}

snGradSchemes
{
default corrected;
}

Now I'm using OpenFOAM 3.0.1. on Linux Ubuntu 14.04. Hope you have some idea about it.

Hi,
you need this in your fvSchemes:

wallDist
{
method meshWave;
}

When the message says "keyword is missing" then the solver expects this keyword in the dictionary. One useful step is to search for the missing keyword in OpenFOAM tutorials to see what the solver might expect, like this: in the tutorial folder: grep -R wallDist
This has nothing to do with a specific turbulence model (k-e or k-o).

Hi TobM

Thanks, it really worked, and the command grep -R "..." really helpful!

[vs1]

Hi TobM,

Where does the solver use this
wallDist
{
method meshWave;
}

Is it new to OF version 3,4,5 ? I mean it was not required in fvSchemes file in OF 2.3.


Thanks

[TobM]

Hi vs1,

I haven't checked where exactly it is used.
It was introduced a while ago.
