Hi everyone,
Greetings. I am trying to simulate a cold flow (no combustion) test case on a step mixer geometry for supersonic flow visualisation using rhoCentralFoam. I have tried different ways by changing the fvScheme and boundary patch names. but the flow is not passing across the combustor. it just reached the step and the simulations getting stopped with an error message appearing as " FOAM FATAL ERROR: Negative initial temperatures" Kindly, please let me know, where could be the error, and what can be the reason. how to approach.. ! Thank you very much in advance..! Please find the case file. Expected result vs my result link for the case file: https://drive.google.com/file/d/1Ca-...ew?usp=sharing my result.jpg Expected result.jpg |

Note, I have tried with OpenFOAM 7 version.
