you may find some remarks if you check the Vallier's PhD thesis. The topic is for bubble formation due to cavitation (similar problem with different application) There is a search algorithm in that....

This sound reasonable. By spatial resolution, I meant the something similar. Because the V_cutoff may depend on your grid resolution. But there is something else you should take care of: Imagine you...

You would need a spatial criterion based on resolution of
Your VoF simulation. This should determine where and when the interface is poorly resolved. Then you would identify those cells as a...

If the solver compiles without error, one possible reason for this problem might be the initial values you provide in the //constant/particleProperties. If I'm not mistaken, this error seems to...

I see. The only thing that I can offer is to use this format:

findTetFacePt(cellI,pt,tetFaceI,tetPtI);

instead of function "findCellFacePt". In this way the cell centers can be represented by...

Did you modify solidParticleI.H as well?
If so, I would say put the error you get here.

In addition, for cell center I guess you may simply use: "findTetFacePt" function or other functions like...

I went through your code and I finally got what's wrong with the impelementation.
In solidParticleCloud.C within the function inject you define the following:

How did you define the scalarField T in this class? The error says you have not defined T yet. Please put the .H and .C files here, then I can see what you have done.

Yes you need to implement it within the function "inject" inside the function "move".
As I said this is not difficult at all, but needs some efforts. Just follow the instruction in the report, If...

If you wanna inject particles per cell (not for instance bubbles or drops which would undergo coalescence/breakup), this can be simply done. You only need to define an injection function in the...

What is your dt and minimum grid spacing (dx)?
I guess it might be due to very small dt times dx in the denominator of momentum source resulting very large values.

Actually you are right, as the solid particle impinges the fluid interface it
will cause splash and the physical change makes no sense. But, just imagine the
