Hello there,
I am new to SimScale and have been experimenting with external aerodynamics simulations for a personal project involving a car body design. While I have managed to set up the geometry and mesh it fairly well, I am struggling a bit with properly defining the boundary conditions to get accurate and stable results.
Specifically, I am unsure about the best practices for assigning inlet and outlet boundaries when simulating airflow over a complex geometry like a car. I have read through the documentation and watched a few tutorials, but I still find myself confused when it comes to the correct placement of these boundaries and how to handle turbulence parameters.
Should I be using a velocity inlet or a pressure inlet in this case? And for the outlet, would a fixed pressure outlet suffice, or should I consider another type?
Thanks in advance for your help and assistance.
