How could I implement tracking of some selected particles in OpenLB?
Hi,
This is a good question; I don’t think there is an easy way of doing this, especially in parallel. We will probably investigate this topic at some point, but currently we are concentrating on other aspects.
Hello johndoe,
you can write your own code for that. It is not straight-forward, though. In principle, the particle is advected by x += u, where u is the velocity at the position of the particle at the current time-step. However, you have to know the velocity of the particle at its position, hence interpolation is required. I am currently working on applications, but I am not using openLB.
If you are still interested, just tell me what you have in mind in particular, then I can give you some references.
