Hi,
That’s a nice Aircraft, but for a High Super-Sonic flow , you will have to use the " Density based" solver in the ‘Compressible’ analysis type. I see that the current runs were with the ‘Pressure based’ solver which is Not designed for such high speed flows.
The ‘density based’ is only available with a ‘Laminar’ turbulence model (for now). So you may go with a Laminar assumption and try with that.
There is some description about the solver in my earlier forum post: Trans-Super Sonic Compressible Flow projects
To select it see the snap below:
Also, you can use non-dimensional values for the variables (velocity, pressure etc).
Best,
Ali
