rhoSimpleFoam unknown RASModel type laminar

tdog · June 6, 2016, 11:40

Hello
I'm trying to do a compressible simulation using rhoSimpleFoam for a laminar flow. The scripts I am using is based on an earlier OpenFOAM version (2.0 I think) as was working there, but I am running the newest version.

When I run my scripts I get the following error:
"--> FOAM FATAL ERROR:
Unknown RASModel type laminar

Valid RASModel types:

12
(
LRR
LaunderSharmaKE
RNGkEpsilon
SSG
SpalartAllmaras
buoyantKEpsilon
kEpsilon
kOmega
kOmegaSST
kOmegaSSTSAS
realizableKE
v2f
)
"
Where my turbulenceProperties is set to the following:

Code:

/*--------------------------------*- C++ -*----------------------------------*\

    turbulence      off;

    printCoeffs     off;
}

As far as I can tell from the documentation (http://cfd.direct/openfoam/user-guide/turbulence/) I am doing it the right wa, what seems to be the problem?

Has nobody tried something similar?

Not sure if you have fixed it yet but the simulationType should be set to "laminar". If you read the above documentation carefully, it is mentioned at the very beginning.

Well, it should look something like this

simulationType laminar;

    turbulence      off;

// ************************************************************************* //

As the error message says, just pick one RASModel from the given list. As you can see, "laminar" is not listed there. If you set simulationType to laminar, it doesn't really mattter what you set RASModel to. Hope that helps!

Arg, thanks for the tip

Just tried, but still got an error message because I then need to supply files for the boundary conditions - because in theory it shouldn't need them because it's running the simulation as laminar, but those are turbulent models, right?

This bug seems to have been fixed "recentely"

check the following Commit: https://github.com/OpenFOAM/OpenFOAM...2940548af3ebb3

If your createFields.H in BuyoantSimpleFoam looks like this:

Code:

autoPtr<compressible::RASModel> turbulence
(
     compressible::New<compressible::RASModel>
      (
          rho,
          U,
          phi,
          thermo
     )
 );

change it to:

Code:

autoPtr<compressible::turbulenceModel> turbulence
 (
     compressible::turbulenceModel::New
      (
          rho,
          U,
          phi,
          thermo
     )
 );

cheers

I can't locate the applications folder in order to change createFields.H. How do I do this?

I am running OpenFOAM via Docker on a Mac. So I don't really see a path or folder for OpenFOAM. I have tried to show the hidden folders, but the OpenFOAM or applications folder still doesn't appear.

RAS

    turbulence      off;

    printCoeffs     on;
}

does it actually read the entries in the RAS part if you specified the simulationType as being laminar?

whats the difference between this:

Code:

simulationType RAS;

RAS
{
    RASModel        kOmega;

    turbulence      off;

    printCoeffs     on;
}

and

Code:

simulationType laminar;

because isn't turbulence off technically just laminar flow?
