Hi, I am trying to simulate a visualisation that portrays Airflow within a building as if it were trails:

I am planning to use Embergen and then export the ABC file to Houdini. I wonder how difficult this is for a beginner? I imagine it is possible, since I still haven't found anything Houdini isn't feasible for.
You can achieve this entirely in Houdini, either by using its pyro/smoke solvers for more physically based results, or by building a simplified setup with the Linear Solver to generate plausible flow around the buildings.

I checked one of the caches and it doesn’t include a velocity field. You can approximate velocity by using Volume Optical Flow SOP between two consecutive caches.

Thanks a lot for this. Is it possible to share the scene? Since I am new doing this I am trying to understand the use of the timeshift. Also what do you call cashe sice I do not see the nodes applied in the screen grab.
Hi. Thank you for this. I think I have a bit better understanding now. But lines seem not to be coinciding with the smoke shapewise. Is this something expected? Thank you
