Cloud Function Objects question?

Dear foamers

I just wonder whether anyone used the VoidFraction under the src/lagrangian/intermediate/submodels/CloudFunctionObjects?

I have a set of two phase flow data (bubble/fluid) with lagrangian tracking and I am trying to calculate the void fraction of the flow field.

I have put the followings in the kinematicCloudProperties:

Code:

cloudFunctions

{

   voidFraction;

}

However, I got the void fraction is zero everywhere in the kinematicCloudTheta:

Code:

dimensions      [0 0 0 0 0 0 0];



internalField   uniform 0;



boundaryField

{

    movingWall

    {

        type            calculated;

        value           uniform 0;

    }

    walls

    {

        type            calculated;

        value           uniform 0;

    }

}

I am not sure where I got it every. I really appreciate any advice suggested.

I have the exact same issue as you, and cannot get it to work either. I have filed a bug report on it: http://www.openfoam.org/mantisbt/view.php?id=829

Hello,

Hello Jie, Did you solved the void fraction issue in CollidingParcel case ? can you please share their file or suggest me where and how to incorporate the line " td.cloud().functions().postMove(p, cellI, dt);" in CollidingParcel.C. Moreover, dt is not mention in the CollidingParcel.H file. so it will give an error while compiling

I am using OF-2.2.2.
