Facing Problem while running a compressible simulation

Project Support

Hi,
I have been trying to run a compressible flow simulation on a model of a de laval nozzle.
Now I have relaxed the equations, changed the pressure solver to GAMG for faster computation and the divergence schemes to Bounded gaus upwind and gaus linear where the previous one not available. But still can’t successfully run the simulation as its shows that the maximum number of iterations have exceed. Now how can I increase the number of iterations in this case?

Hi Tasdid,

will have a closer look at this later on. One thing that might help here though. You can cut out 10° or less and use wedge patches in order to save time. If you do not know what that means, I can show you later on.

Best,

Will try the wedge boundary condition, lets see if its resolved

Hi Tasdid!

Now I am at my machine :slight_smile: Here you go: Laval Nozzle Simulation

Cheers and let me know if you need any additional help!
