aamer Member Aamer Shahzad Join Date: Mar 2010 Posts: 58 Rep Power: 16	Hello all.... i am running a case where in coming mach number is 0.4, which falls in the compressible regime (M>0.3). according to fluent user guide, pressure based solver is preffereable for incompressible flows and density based solver is preferable for compressible flows. IS it possible for me to use pressure based solver for mach 0.4 ? i will of course switch ON energy equation for it. or is it a compulsion on me to use density based solver because of compressible regime ?
