CFD - PERRINN F1 Car (w/ spec mods)

[MKRaven]

Hi all,

Some question to creators of this topic, who did some magnificent job:
I am doing quite the same, meaning trying to run a CFD for PERRINN model for my MSc. Even got approval to use some dedicated workstation at work for this process.

Yet, I am having trouble simplifying geometry. Especially sidepods and curvature around side intakes is causing a lot of trouble, even when I trie to merge it all. SpaceClaim and Fluent + Inventor in use and can't figure aut how to go around it, besides redrawing whole model.

We also had a lot of issues cleaning the car up for CFD. It just takes time to get to a useable state.

Thats some wonderfull work done here! Thank you guys very much! I wish there would be something like that available about the era of 1996-2006, as i am working on a book about this era!

me too
(not the book - the wishing for old car cad)

Otherwise, sounds good, I think it will yield some really interesting results.

Alrighty, I've built the CFD method up now, so I will document the exact values etc. that I used for each of the frame references and boundary conditions (100m corner radius @ 50m/s), and then give it a shot at implementing it over the weekend with some CAD updates... again, depending on my free time

Took me a couple hours to figure out the correct reference frames and BCs to use in the ANSYS environment, but hey - I made a rainbow

Thanks heaps for the tip mate, really cool to add this to my tool belt of things I can do

Hi, I am doing my thesis on a cfd analysis of a wing and I would like to know how to implement on ansys fluent the moving reference frame and the correct boundary conditions as you did with the cuboid domain. I am new to cfd and am learning as I go.
