Dear  Philipp,

Thanks for your your suggestion to correct my model which I really
appreciate. I want to explain what I am doing and could you please give me
some advice. Thanks so much.

Now I am doing a Lagrangian particle tracking model with two-way coupling.
So the interaction between two phases in my mind, should be added to the
Eulerian grid point where the particle is, and the grid point where it
belongs to is what I was finding out. I am sorry to say that I don't
totally understand the the regularising the force among a number of grid
points. I read some IBM papers before. If I were correct, I think the
regularised function is employed with interpolating velocity and
regularising force among adjacent grid points to keep the interface smooth.
Do you think for my piont-particle tracking the regularising is needed?
Would you please give me any suggestions?

Kind regards,

Jian
