Hello guys, I’m currently doing an aerodynamics simulation to simulate the airflow around a missile using the compressible flow simulation.

Somehow, for this model only, the sim runs are constantly failing. I’ve changed my walls to adiabatic, and meshing quality to 8, but the errors keep showing up. Any help for the problem?

Thanks,  
Danson
