Okay so i have followed this video, and it made the simulation run. But the particles doesn’t work like in the video, could anybody help me with this problem? Take a look at simulation run 1. I’m a beginner, so please help me. Thanks!
Video i followed: External Aerodynamics of an Ahmed Body - YouTube
Hey @magn8838,
Please review your boundary conditions. You got velocity and moving wall directions wrong.
The particle trace setup was fine though.

So i should do the boundary conditions over? Or what is it I should do. Would you like to help me out?
What you Ricardo meant is to change the velocity BC. Change it from z to x, just have a look at the coordinate system and you see where the flow should be.
Best,

Okay, but when i did so. I tried to make a new simulation, but then it wouldn’t run. It said that i had to reduce my mesh fineness.
