Filter solids by phase in Monitors

While using Lagrangian monitors, is there a way to filter the monitor based on particle phase? Basically, I have two different “types” (phases) of particles in the system, and I want to monitor their phase-dependent property over a region, e.g., average velocity of phase 0 and average velocity of phase 1 separately etc. Is this capability available out of the box, or requires source code change?
Thanks!

Hi Ishan,
this capability requires source code changes.

Thanks Roberto! I kinda figured that, but just wanted to make sure if something like this was in the offing.

Robeto has helped me hack something in before that filtered one single particle, I might be able to dig that up if it would help.

But also I just wanted to second your request, it would be nice to filter monitors in general with a mask. I realize that would take some dev work, but maybe @jmusser would consider it for future high priority dev needs.

Thanks Will. I was able to hack something in myself to get it to work last week. Basically, I created a mask that filters Lagrangian monitors based on the “phase” of the particle, which is what I need at the moment. I agree that there will be a lot of value in a general mask (esp. for particles) that filters based on combinations of particle attributes defined through the inputs file.
