Hello Forum,

I am running a 3D simulation of a cavity with rigid stones inside (10 stones of size 0.03*Radius_cavity). I want to show how the stones disrupt vortex. But I am struggling to get a "metric" to show this.

I have thought about the following, but I am not totally sure if this makes sense to you:

* Calculate the Q-criterion
* Find the volume of fluid inside the cavity with Q>0 (vortex-dominated region)

This volume of fluid corresponds to that one in which vorticity dominates over strain.

By comparing the volume between the no-stones simulation and simulations with stones, I could see the disruption of vortex as a result of the stones

Thanks in advance
