You need to use the same number of prism layers on both parts, otherwise, there's no way in the world to avoid stairstepping..

You've got two options:

1. decrease the surface element sizes in this region so there's no stairstepping (don't know if WB Meshing has options for max aspect ratio and gap factor of prisms like...

That pdf was just a collection of questions and things I had done up to that point.. It's not really of much use (it wasn't a step by step guide or anything). If you are doing vehicle aerodynamics,...

If the objective is to study the effects of the exhaust gases on the airflow around the car, then I'm guessing it'd be enough to have a full solid pipe (cylinder) that exists where it does on the car...

I used the Standard Initialization and Compute from velocity-inlet. As I've said, I'm keen to learn some proper Fluent solver setup because I'm using the most basic settings with the SIMPLE scheme...

Small update while I wait to be educated on solver setup.. :)

I finished the simulation with a ~6 million element grid and wasn't really sure on the velocity over the rotating tires, so I repeated...

Hm, yes.. I've read that it is possible to batch these types of simulations on parameters. But how would the meshes handle that? Would the mesher automatically remesh every time? Basically, what I...

Last update for now, as I'm going to run a simulation for the next oh.. 12-24 hours.

I've managed to create two bodies of influence, one that captures the undertray and the wheel wells of the car,...

It seems you were typing during my last edit :) In any case, I managed to solve the body of influence problem. Thank you for that article, I will go through it when I start the simulation run.

Yes, turns out I'm an idiot again. It was enough to insert a sizing method and pick a single vertex at the rear of the car, then define sphere radius and max element size. I'm gonna try moving it...

Dear Stuart,

First off, thank you! I've had a bit of a break through yesterday. Let me explain.

I tried to run another simulation with the first set of tires (the ones with just the flatspot)...

Simplified vehicle model (wheels intersection, density region)

Hello,

I won't be writing a lengthy post, instead I'll attach a .pdf that I've put together explaining where I'm stuck. Maybe it can help someone other beginner in the future.
