I am currently encountering challenges related to computational convergence, and I am uncertain whether the issue stems from grid quality, boundary conditions, or the chosen computational methodology. I had tried using the first order scheme or reduced CFL number, but nothing works. To facilitate a comprehensive understanding of the situation, I have provided my mesh and configuration files below. Any assistance or insights into resolving this matter would be greatly appreciated. Thank you in advance for your valuable help. Best regard, Zhang. config file: https://drive.google.com/file/d/11sy...ew?usp=sharing mesh file: https://drive.google.com/file/d/1bTY...ew?usp=sharing Last edited by Amber0922; December 17, 2023 at 23:43.
