Way from OfenFoam 1.5 to 1.6
 
Hi,
I'm a french student and i'm new in the CFD domain.
I have installed OF1.6 without problem, I had too OF1.5.
I have build the rhoSimpleFoam files of OF1.5 and it was good. But now the same files don't work with OF1.6.
Why ?
Is ti normal that i don't have the rhoSimpleFoam tutorial after the installation ?
Does someone have this rhoSimpleFoam files for OF1.6 ?
Thank you
Simon :cool:

There are few changes u need to make to run OF 1.5 files in OF 1.6. the one thing I found was u need to change in fvSolution dictionary in system directory where U need to write the solver as seperate entry.

Ex:
In OF 1.5 u have

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

In )F 1.6 u need to write

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

with OF-1.6 some solver are removed as they not necessary as turbulent options (RANS/LES/laminar) are available in every solver, please go through 1.6 release notes

Yes i have observed this problem und corrected.

But my problem is the following :

"
Reading thermophysical properties

Selecting thermodynamics package hPsiThermo<pureMixture<constTransport<specieThermo <hConstThermo<perfectGas>>>>>
Reading field U

Reading/calculating face flux field phi

Creating turbulence model

Selecting RAS turbulence model kEpsilon
kEpsilonCoeffs

Cmu 0.09;
C1 1.44;
C2 1.92;
C3 -0.33;
alphah 1;
alphak 1;
alphaEps 0.76923;
sigmak 1;
sigmaEps 1.3;
Prt 1;
}

Thank you for your answer

The error message seems pretty self-explanatory. Have you defined div(U,p) in fvSchemes?

No, not at all in fvSchemes.
I have never seen this line.
I need to use this rhoSimpleFoam solver because i want to have "steady-state solver for turbulent flow of compressible fluids".

Have you tried defining it in fvSchemes? I'm not sure why you get this error in 1.6 and not 1.5 though.

Yes it answers the same thing !
Thank You

Someone has the files for this tutorial (rhoSimpleFoam) ?
