Hi,
In my work I am modeling a compressible flow in Fluent and I am wondering if I can use pressure density solver. In my model I have a time dependent flow where the Mach number could reach a value about 2. As its is a transient simulation I first try to run a model in steady state to have a good starting point for the transient analysis

Both pressure and density based solver have the capability of calculating compressible high Mach number flows. If you want further advice, please provide details on your problem set up.

In early days of ansys, the density based solver was designed particularly for compressible flows. but now a day both solver works fine in both compressible and in compressible flows. But inherently sometimes density based solver yields better results than pressure based
