      Hello,

      I am using CESE and Chemistry model for multi-species transport. I simulated a hydrogen-oxygen detonation using Cese, setting the initial pressure to 0.3 MPa and temperature to 300 K, with non-reflective boundary conditions. However, the pressure curve I calculated differs significantly from Fluent's results, and the pressure doesn't drop to atmospheric pressure during stabilization. How should I address this issue?

      Regards
