For the view in 21:10 If the angle of attack for the rear element was very severe, what kind of arrows would we see to observe flow separation? Also, lets say we have a vortex generator on the wing, how does the simulation correspond for the streamline visualizations?
Flow separation would be predicted if the arrows were not parallel to the flow surface. Streamlines would be a good way to show vorticity. There is also a vorticity output request.
I would like to try this but in steady state. Do you have tutorial in another video how to setup for steady state? Because in multiphysics the solver's default is transient, and when changing to steady state the solution give error result
@@Simcenter3DTipsandTricks yes sir, I…am working to contribute to my capstone, and am using a combined flow and structural simulation to simulate a simple 4412 airfoil with a wing tip attached to the body. The program actually throws no errors - I am receiving the error message: “Error: Mapping input file could not be created. Check file permissions”. The software license at my school is replaced each year, but I’m not sure if that is what the issue is. I got the air mesh to work, it took me forever to correct my 2D Mapped Mesh over the airfoil surface, but I did it. My last check is to ensure it’s over the whole rest of the 2D wing mesh I am using, but otherwise I am no longer receiving body or meshing, material or initial condition issues.
@@Simcenter3DTipsandTricks but yes! For the longest time my issue was the air mesh, and it was because it was throwing issues when using the infer bodies command. I didn’t have a 2D mapped mesh over the wing then, but even still I believe I ended up having to use the until next option, where I selected the opposite end of the volume

Thank you for the reply, very much appreciated@@Simcenter3DTipsandTricks

You could try it the old fashioned way shown here: ua-cam.com/video/LjDW19Et_gY/v-deo.html
No matter what I do I cannot generate a 3d mesh of the air
Do you have a solid body that represents the air?
