Hi everyone,


The update to the latest version of openFoam seems to have broken the postprocessing I was using for boundaryFoam. Its based on the surface mounted cube casefile, which no longer will run:

functions
{
    turbulenceFields
    {
        type            turbulenceFields;
        libs            ("libfieldFunctionObjects.so");
        writeControl    writeTime;
        fields          (R nuTilda k epsilon omega L);
    }

    surfaces
    {
        type            surfaces;
        surfaceFormat   boundaryData;
        writeControl    writeTime;
        interpolationScheme cell;
        fields
        (
            U
            turbulenceProperties:R
            turbulenceProperties:nuTilda
            turbulenceProperties:L
        );
        surfaces
        (
            inlet
            {
                type            patch;
                patches         (inlet);
                interpolate     false;
            }
        );
    }
}

This code gives me: --> FOAM FATAL ERROR: Unknown write type "boundaryData"



If I change the type to something valid, I get:

--> FOAM FATAL ERROR: 
attempted assignment to self

    From function void Foam::DimensionedField<Type, GeoMesh>::operator=(const Foam::DimensionedField<Type, GeoMesh>&) [with Type = double; GeoMesh = Foam::volMesh]
    in file /home/ubuntu/OpenFOAM/OpenFOAM-7/src/OpenFOAM/lnInclude/DimensionedField.C at line 520.

Does anyone know what happened, and how this is supposed to work now? I don't see any tutorials in the current release using boundaryFoam that actually map the output or use function objects.


Thanks

Hi Abe,

Did you figure it out? I'm having the same problem.

[KTG]

I did not, but I may have been using mismatched versions of OF and the tutorials. What version are you using? I am still on 1906 and the surface mounted cube tutorial runs without error, so I am guessing there was a change in syntax somewhere along the way.

[MaySea]

I'm also using 1906. Wanted to use this code to sample data at outlet and got the same error ( FOAM FATAL ERROR: Unknown write type "boundaryData") :

sampledPlanes
{
type surfaces;
functionObjectLibs ("libsampling.so");
outputControl adjustableRunTime;
outputInterval 100;
enabled true;

surfaceFormat boundaryData;
fields (omega k);

interpolationScheme cellPointFace;

surfaces
(
center
{
type patch;
patches ("west");
interpolate false;
}
);
}

[KTG]

Ahh, that is a separate issue. "boundaryData" is not a valid surface format. There are a number of ways to achieve what you are trying to do. Try the method of putting "banana" in place of "boundaryData", and the solver output will crash and give you a list of valid entries.
