LPT-VOF coupling in OF 7

[qingdong_wang]

大家好， 现在在做LPT和VOF耦合， 既把solidParticle植入到interFoam中。 我现在有的参考还是chamlers根据openFoam 3.0 做的， 但是他在OF7 中并不匹配

void Foam::solidParticleCloud::inject(solidParticle::trackingData &td)
{
label cellI=1;
label tetFaceI=1;
label tetPtI=1;
mesh_.findCellFacePt(td.cloud().posP1_, cellI, tetFaceI, tetPtI);
solidParticle* ptr1 = new solidParticle(mesh_, td.cloud().posP1_, cellI,
tetFaceI, tetPtI,td.cloud().dP1_, td.cloud().UP1_);
Cloud<solidParticle>::addParticle(ptr1);
mesh_.findCellFacePt(td.cloud().posP2_, cellI, tetFaceI, tetPtI);
solidParticle* ptr2 = new solidParticle(mesh_, td.cloud().posP2_, cellI,
tetFaceI, tetPtI, td.cloud().dP2_, td.cloud().UP2_);
Cloud<solidParticle>::addParticle(ptr2);
}

这个是加入到solidParticleCloud.H 的代码， 然后显示member function cloud 不存在，然后我去看了particle.H 中的代码，

class particle
:
    public IDLList<particle>::link
{
    // Private member data

        //- Size in bytes of the position data
        static const std::size_t sizeofPosition_;

        //- Size in bytes of the fields
        static const std::size_t sizeofFields_;

        //- The factor by which the displacement is increased when passing
        //  through negative space. This should be slightly bigger than one.
        //  This is needed as a straight trajectory can form a closed loop
        //  through regions of overlapping positive and negative space, leading
        //  to a track which never ends. By increasing the rate of displacement
        //  through negative regions, the change in track fraction over this
        //  part of the loop no longer exactly cancels the change over the
        //  positive part, and the track therefore terminates.
        static const scalar negativeSpaceDisplacementFactor;


public:

    class trackingData
    {
    public:

        // Public data

            //- Flag to switch processor
            bool switchProcessor;

            //- Flag to indicate whether to keep particle (false = delete)
            bool keepParticle;


        // Constructor
        template <class TrackCloudType>
        trackingData(const TrackCloudType& cloud)
        {}
    };

发现trackingData已经没有private成员和member function了，OF5中还是有的， 如下

class particle
:
    public IDLList<particle>::link
{
    // Private member data

        //- Size in bytes of the position data
        static const std::size_t sizeofPosition_;

        //- Size in bytes of the fields
        static const std::size_t sizeofFields_;

        //- The factor by which the displacement is increased when passing
        //  through negative space. This should be slightly bigger than one.
        //  This is needed as a straight trajectory can form a closed loop
        //  through regions of overlapping positive and negative space, leading
        //  to a track which never ends. By increasing the rate of displacement
        //  through negative regions, the change in track fraction over this
        //  part of the loop no longer exactly cancels the change over the
        //  positive part, and the track therefore terminates.
        static const scalar negativeSpaceDisplacementFactor;


public:

    template<class CloudType>
    class TrackingData
    {
        // Private data

            //- Reference to the cloud containing (this) particle
            CloudType& cloud_;


    public:

        // Public data

            typedef CloudType cloudType;

            //- Flag to switch processor
            bool switchProcessor;

            //- Flag to indicate whether to keep particle (false = delete)
            bool keepParticle;


        // Constructor
        TrackingData(CloudType& cloud)
        :
            cloud_(cloud)
        {}


        // Member functions

            //- Return a reference to the cloud
            CloudType& cloud()
            {
                return cloud_;
            }
    };

我看官方貌似对particle和injection做了挺多改变的。请问一下有大神对这个有所涉及或者可以给个hint吗？

你可以直接用MPPICInterFoam试试

[qingdong_wang]

@东岳 但是那个貌似是在v1906这种版本，我现在用的是OpenFoam 7, 貌似没有MPPICInterFoam
