Greetings all!

I am working on a problem related to aerospike nozzle. There are reflected mach waves in CFD results. These reflected waves increase the CFD mach # initially, and later reduce the mach, as they reflect from the free boundary (see attached figure).

I need to account for these reflected waves numerically in the fluent software, such that there are no reflected waves from the spike wall or from the free-boundary.

Are there any conditions in the solution methods of fluent, which may enable me to achieve my purpose?

Thanking in advance,
Safwan, from Pakistan
