Class
    Foam::codedMixedFvPatchField
 
Group
    grpGenericBoundaryConditions
 
Description
    Constructs on-the-fly a new boundary condition (derived from
    mixedFvPatchField) which is then used to evaluate.
 
    \heading Patch usage
 
    Example:
    \verbatim
    myPatch
    {
        type            codedMixed;
 
        refValue        uniform (0 0 0);
        refGradient     uniform (0 0 0);
        valueFraction   uniform 1;
 
        redirectType    rampedMixed;   // name of generated BC
 
        code
        #{
            this->refValue() =
                vector(1, 0, 0)
               *min(10, 0.1*this->db().time().value());
            this->refGrad() = vector::zero;
            this->valueFraction() = 1.0;
        #};
 
        //codeInclude
        //#{
        //    #include "fvCFD.H"
        //#};
 
        //codeOptions
        //#{
        //    -I$(LIB_SRC)/finiteVolume/lnInclude
        //#};
    }
    \endverbatim
 
    A special form is if the 'code' section is not supplied. In this case
    the code gets read from a (runTimeModifiable!) dictionary system/codeDict
    which would have a corresponding entry
 
    \verbatim
    myPatch
    {
        code
        #{
            this->refValue() = min(10, 0.1*this->db().time().value());
            this->refGrad() = vector::zero;
            this->valueFraction() = 1.0;
        #};
    }
    \endverbatim
