http://sdcd.gsfc.nasa.gov/ESS/exchange/contrib/deane/ddcon2d.html ddcon2d - Double-Diffusive Convection Code Using a Pseudo-Spectral Method <author> <version> <abstract> ddcon2d solves the two-dimensional Navier-Stokes equations for Boussinesq convection by Fourier Galerkin + Collocation method. The system models double-diffusive convection in which two agents (e.g. heat and a solute) have opposing contributions to the bouyancy and diffuse at different rates. The problem is of relevance to oceans (heat + salt) and mixing in stars (heat + angular momentum, heat + concentrations etc.) It has been studied extensively in the laboratory, under different guises. The current set-up models the occurence of various waves (standing and traveling convection waves) <contact> <keywords>spectral method; hydrodynamics; application program <category>application <publication-date> <environment> <method>Fast Fourier Transforms, spectral method <application>hydrodynamics <comments> </urc>
