Need Help With Mesh Set up

Drag Coefficients

• I am trying to achieve accurate values for Drag Coefficient. current simulations produce values of 0.001 whilst expected values are 0.3-0.5. Unsure on where I can improve but I have been struggling with mesh production. I have even followed some of the Simscale tutorials but they have also been unsuccessful.
• I have tried to create multiple meshes. All of these meshes have still yielded inaccurate results
• Here is the project link:

I would really appreciate help on this project as I am new to meshing and Simscale CFD
Thanks a lot

Hello rduunings,

Seems like this is now a duplicated forum thread, I have attached the other thread and will mark this one s a solution,

Unexpected Drag coefficients

I have been spending quite some time whilst attempting to simulate this vehicle. The drag coefficients do not match with other results and neither do the drag forces. Any help with the simulation set up would be great. All environments in other simulation software are identical to the environment I have created on Simscale. *Trying to calculate a drag coefficient The results do not match up with similar set ups in other CFD software. These results give a coefficient of 0.08 whilst the expec…
