Hi, guys.

Now, I have simulated the indoor room.
Particles are injected in the room.

Now, I want to know how to get a Particle concentration at any point.
Finally, I will compared a particle concentration at each point in experiment and simulation for simulation validation.

Is there any way to know the particle concentration at the point?

In derived part you can create a probe, point (give the x,y,z position)
create a maximum report using the part (you just created, point probe) and scalar is volume fraction of...(name you gave)

Might want to check the smooth box in the report, it will interpolate to that position instead of a cell-center value,

Sometimes it might be better to use a part of your volume mesh, create a threshold and use volume average report, this way if there is some uncertainty into what position your probe is, you are getting an average value,

Could you please post your code under the function.
I am really appreciate.
