Simulation problems undetected?

hello, I have just completed a simulation and the results are not correct. the mesh was fine the boundary conditions were fine and still the simulation completed and gave a wrong answer. I have no clue as to why this is occurring, could you please help me pinpoint the error so I can fix it?

thank you so much,

Hello,

Have you already tried to activate potential flow initialization? This tends to help a lot with external aerodynamic cases:

PS: I’d expect the top, bottom and side walls to be “Slip”, and not “no-slip” (your third boundary condition).

Since the other post that you opened a while ago is related to the same problem, I’ll close the other one for the moment.

Cheers

I was inspecting my simulation halfway through when I noticed something weird happening to the inlets do you have any idea what is causing this?

thank you for your time and help,

lol sorry for the trouble I can’t believe I didn’t notice that it was on no slip😆. But I didn’t know about the potential flow organization.

Thank you so much and have a fabulous day,
