Steppin'

The code I've been working on for, quite literally, years is finally coming together.  It's called Suzerain.  Suzerain is a mixed Fourier, B-spline spectral DNS code for solving the compressible Navier–Stokes equations for a perfect gas.  Nearly every technical thing I've written on this blog has been about it in some way.

My first sanity check has been advancing a quasi-1D, laminar channel flow profile to a steady state condition. Some plots follow with units nondimensionalized by the bulk velocity, channel half width, and wall temperature and pressure. The initial conditions were constant density and temperature along with a parabolic velocity profile. Happily, the simulation relaxes the way I expect.

Onward.

Glad your project is coming together nicely, very impressive.
