[FLASH-USERS] Homogenoues Isotropic Turbulence using StirTurb case

Hello everyone,

I am planning to use Flash for the Homogenoues Isotropic Turbulence. In the
Hydrodynamic test problems under *The Supplied Test Problems, *I saw
section 34.1.9: Driven Turbulence "StirTurb" in the Flash user guide.

I thought of using it, but I doubt whether it solves Navier-Stokes with
diffusion term. Because in chapter 14: Hydrodynamics units, the
guide mentions that "The Hydro unit solves Euler's equations for
compressible gas dynamics...".

Has anyone used Flash for incompressible pure hydrodynamic problems? Can
flash be used for the Homogenous Isotropic turbulence problem? Please let
me know if I can provide additional information for the issue mentioned.

Thanks and regards,
Akash Rodhiya
