Fatal error when running cfd simulation

When trying to run a cfd of my f1 car design, the mesh generates perfectly fine, but when going to run a simulation I get an unknown error.

thanks in advance for any help :slight_smile:

Hi 18zsmith,

thanks for reaching out to us here in the forum.

I checked your simulation and i saw that you have 83 Mio cells in your mesh, which is very high.
This would mean that your simulation takes very long to finish. ( Try to go for something less then 1 Mio. cells for the start.

Maybe you can have a look at the meshing of a formula student car tutorial.

Of course you would have to scale it down to fit your car.
Also try to make use of the symmetry of your object, also as in the Tutorial.

Best regards Sebastian
