const fvMesh& mesh = refCast<const fvMesh>(this->db());

赋值建议采用

operator==(field);

具体可以参考codedFixedValuePointPatchField.H的注释

Example:

movingWall
{
    type            codedFixedValue;
    value           uniform 0;
    name    rampedFixedValue;   // name of generated bc

    code
    #{
        operator==
        (
            vector(0,0,1)
            *min(10, 0.1*this->db().time().value())
        );
    #};

    // codeInclude
    //#{
    //    #include "fvCFD.H"
    //#};

    // codeOptions
    //#{
    //    -I$(LIB_SRC)/finiteVolume/lnInclude
    //#};
}
