'BRZ Aerodynamics Scaled' simulation project by lesterneo


#1

I created a new simulation project called 'BRZ Aerodynamics Scaled':

Scaled version


More of my public projects can be found here.


#2

True to scale geometry used.

Auto snappyHexMesh for external flow. Problems encountered with anything higher than level 1 meshing.

Hi @lesterneo

I just copied your project and created a “New Auto SnappyHex Mesh” with “level-3 Moderate” fineness and there were no problems. Could you be precise what happened in your case ?

Please try again by creating a New “Auto SnappyHex Mesh” with “level-3 Moderate” fineness with 16 processors.

Let me know if you still have issues.

Ali

Also, Your geometry is a highly detailed, I would suggest that you simplify it to remove non-important things like the roof antenna, wind screen wipers , other small parts etc, if possible.

Other wise try a Manual “SnappyHexMesh” with full control over refinements ,

A basic tutorial is here : https://docs.simscale.com/docs/content/preprocessing/meshing/snappyHexMesh-ahmed-flow.html
A Sample project with Manual “SnappyHexMesh” : https://www.simscale.com/projects/Ali_Arafat/aerodynamics_analysis_of_a_formula_one_f1_race_car

I hope this helps.

Thanks for taking a look at this simulation Ali, was just using the comment section to keep notes on this project. Didn’t expect anyone to respond. :yum:

Anyway, I will give both the level-3 moderate a try and manual meshing refinements a try as well.

Hi @lesterneo

Its good to see your level-3 mesh went successful. Be sure to tag me by typing " @Ali_Arafat " so that I can get a notification of the conversation.

let me know if you need any help. ok

Best,
Ali
