Hello,


Could you please try and use First Order Upwind for both Turbulence parameters? Also, can you please try the Hybrid Initialization? Once you finish your Hybrid Initialization, could you please initialize using FMG? You can do this using the following TUI command.


/solve/initialize/fmg-initialization


Also, could you please reduce your under-relaxation parameters to see if you can get convergence?


Another suggestion - you could run the first-order discretization for pressure in the beginning. Once you have a convergence solution, could you please switch the pressure to Second-Order upwind and try?


Please change the 'Pressure-Velocity Coupling' to Coupled and then you should be able to check the 'Pseudo-Transient' option. This might help. Which Fluent version are you running?


Thanks.


Best Regards,


Karthik
