calculated 边界条件怎么用?有谁知道啊?



  • This boundary condition



  • 你不需要指定其他信息,这样即可:

    type calculated;
    


  • FoamFile
    {
    version 2.0;
    format ascii;
    class volScalarField;
    object p;
    }
    // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

    dimensions [1 -1 -2 0 0 0 0];

    internalField uniform 3e+06;

    boundaryField
    {
    INLET
    {
    type calculated;
    }

    WALL
    {
        type            zeroGradient;
    }
    
    OUTLET
    {
        type            calculated;
    }
    

    }

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



  • FoamFile
    {
    version 2.0;
    format ascii;
    class volScalarField;
    object p_rgh;
    }
    // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

    dimensions [1 -1 -2 0 0 0 0];

    internalField uniform 3e+06;

    boundaryField
    {
    INLET
    {
    type fixedValue;
    value uniform 10e+06;
    }

    WALL
    {
        type            zeroGradient;
    }
    
    OUTLET
    {
        type            waveTransmissive;
        value           uniform 3e+06;
        field           p;
        gamma           1.17;
        phi             phi;
        rho             rho;
        psi             psi;
        lInf            0.05;
        fieldInf        3e+06;
    }
    

    }

  • 这样设置好像不行啊@cfd-china

    这不是因为边界条件导致的哦。估计是除以0了:sunglasses:
