We see that FLUENT offers two methods ("solvers") for solving the governing equations: Pressure-Based and Density-Based. To figure out the basic difference between these two solvers, let's turn to the documentation.

Since we are solving a high-speed compressible flow, let's pick the density-based solver.
In the Solver menu, select Density Based.
Under Space, choose Axisymmetric. This will solve the axisymmetric form of the governing equations.
Click OK.
Define > Models > Viscous
Select Inviscid under Model.
Click OK. This means the solver will neglect the viscous terms in the governing equations.
