How did using different colours for each frame help? Different colour
particles maybe, but different coloured frames in post-processing?

You were using particles of differing size and shape? I find that
interesting, how do you know the different shapes were accurately
modelling the flow of the water? In our case we are working with
viscoplastic materials.

I am very interested. Thanks! Anything else that you would like to
tell would be interesting, I am new to the field and just starting to
get a handle on it.
