Setting up a simulation for a compression corner

Serene

Hi,

I am facing a lot of problems trying to run a simulation for a compression corner. I am trying to simplify my approach right now, and is assuming an inviscid and compressible flow. I use the density-based solver, and i believe that i should use set my inlet as a pressure inlet. however, setting my inlet to pressure inlet makes it difficult for me to define my mach number at the inlet boundary.

how can i make sure i get a mach number of say, 2,at the inlet boundary?
