Simulation run failed

Hi, i’m new using Simcale, and i have a doubt in the simulation.
. Can anyone help me to solve this problem?

Another suggestion from my side would be to model only half of the geometry, in order to reduce computational cost, or invest in a better mesh around the vehicle. For example have a look at this tutorial:
