Dear Ansys staff and fellow users,

In regards to the External Aerodynamic Analysis of an FSAE Car Using Ansys CFD series, Lesson 1, at about 10:07min into the video:

&list=PLtt6-ZgUFmMLjplzWHZ9aObvd3n9_sBQ9&index=2

The video doesn't explain in clearly how to fill the surface in between the rim and the wheel (assuming you have you), along with removing sharp corners at the flange of the rim .

Here is the wheel from my car model I'm working on:

Thanks,

Kelvin

Hi Kelvin, 

You can use the Fill tool in  Design tab to fill in the hollow wheel. For removing sharp edges, you can automatically identify and remove those from Detect tool under Prepare tab. 

Ansys Discovery – Detect Tool | Ansys Knowledge

Let me know if this helps.

Hi Devendra,
thanks for helping.

I tried selecting all the surfaces of the tyre, then pressed fill, but it didn't fill.

Thanks,

Also,

I am trying to make my nose completely solid, by selecting all its outer surfaces, by using the fill tool, but it is not working.
any tips? 

Thanks again.

Hi Kelvin, 

Did you try the solidification options in the Repair tab? You can try stitch/missing faces to see if those helps.

Hi Devendra,

I ended up using the solidification tool for the nose, I couldn't still the gap in the wheels. I ended up creating a revolved part to fill in the gap in the wheel, but it has intersection geometry with the tyre itself, so I skrinkwrapped the part + the tyre.

 

Thanks

Hi Kelvin, 

Did the shrinkwrap help with filling this?

Help again please.

On my newer model, I am unable to remove spilt edges via the green tick button, and individually clicking on each error (only worked for one of them).
Imported from Solidworks 2024 model to 2025 R1 Discovery.
Tried the other repair tools, no issues.
The intersecting faces on the solid body are made flush in solidworks.

Tried using the pull tool (round), which got rid of the lower spilt edge at the front of the car, but short edge appears and I’m able to get rid of it.

 

Thanks!

Hello, 

This is direct way of doing it, sometimes software might not be able to automatically fix it and we might need to use manual ways. 

You could try deleting neighbouring faces and solidifying those using Stitch, missing faces. Then again try using the split edges tool.

Devendra
