Thanks for getting back to me. If you can take a look at my project again, would the perforated_duct corrected and convective heat transfer 4 reflect your comments?
I’m still confused on what is the difference between the incompressible and convective simulation options for this project? Additionally, when would one use a geometry primitive? I’m a beginner, apologies if these questions are too simple for this forum.
unfortunately, it seems like the link to your project is not working anymore.
And no problems to your questions, we all have started at some point.
To answer your question, the incompressible solver can solve gas until Mach 0.3 with assuming constant temperature.
the convective heat transfer solver, can also solve temperature changes within the fluid.
You mostly use geometry primitives to create mesh refinement regions. All other Cad geometry you usually provide with the CAD Upload.
when I have a look at your setup. I notice that you have faces which is the outlet of the pipe.
Whenever you define an outlet, the air will exit the fluid domain and therefore will not be taken into account when simulating the air flowing into the box.
Therefore after creating the external fluid volume delete the CAD parts, so that you are left with only the air volume.
You can keep the setup for the inlets and outlets of the pressure outlets for the sides.
Also, make sure that the mesh is finer enough for the perforated holes.
If your simulation is diverging you can also use this method to detect bad regions.
