Define a group of particles out of a bigger group of particles

circles

Hi,

Let's say we have initial set of particles. How would we we assign different mk to some of those particles?

So, if I have N number of particles initially (mk=1) , I want let's say 10% of those particles(randomly selected) to have mk=2.

Could someone point out the direction I should follow?

Thank you.

This is not possible, unless you use your own particle generator and find a way to upload your particle distribution to the DualSPHysics program. I hope that someone from DualSPHysics team will produce a video about how to, but for now you can play around in the code and look in "ToVTK" to find examples of how to do.

Kind regards

What would be the purposes of this random distinction ?

Let's say we have a plate and a region on the plate that attracts those sub-group of particles and I want to observe how those particles accumulate around that region.

OK thanks. No solution for you, sorry
