Hi,


I have noticed that decomposePar changes the boundary conditions, which is very annoying if you want to use many cores.


For e.g. it changed:

    outlet
    {
        type            waveTransmissive;
        field           p;
        psi             thermo:psi;
        fieldInf        101325;
        gamma          1.4;
        lInf            1;
        value           uniform 101325;
    }

To:

    outlet
    {
        type            waveTransmissive;
        gamma          1;
        fieldInf        101325;
        lInf            1;
        value           nonuniform 0();
    }

If I use gamma 7/5 I get gamma 7 in the end.


Can anyone tell me how to solve this problem? I use openfoam4.1.

Inmteresting - apologies for this.


I have checked the mapper constructors for all components, but I cannot see that gamma is not copied. In fact, it looks to me that the code is right.


Can you please give me more details: code version, a case I could look at (ideally, a tutorial) etc?

P.S. Feel free to E-mail me directly.

Thank you for your kind help.


I have attached an edited tutorial case (forward step) from rhoCentralFoam. I have added the inlet and outlet boundary conditions in a way I am using them. The rest is untouched. I have also added a decomposeParDict.


In the folder of the processors you can see the changes of the boundary conditions. I have noticed it only by accident. I have also noticed, that the operation renumberMesh leads to the same phenomenon.


I am using openfoam4.1. I have downloaded it from openfoam.org. I have tried it with openfoam5 and openfoam7. The error still remains.


I can only upload up to 0.2 MB, so I have uploaded it on this website:

Thanks again for the help!

Did you find some time to have a look at it?



Or would you rather have it sent via e-mail? I just dont know how to attach a file with the forum's e-mail function.
