Spectral Element DG and the Convection Diffusion Equation
I'm trying to solve the Convection Diffusion equation for the well known Natural Convection in a 2D square cavity problem (insulated top and bottom, Hot Temp and Cold temp on the Left and Right walls). I'm using a spectral element Discontinuous Galerkin method. I am treating the advection term in a flux form (i.e. (T) ). I am also using a central flux for the numerical flux that arises from the doing the weak formulation. Any ideas or references(other than Warburton/Hesthaven) that could me formulate the right form for the boundary condition for the T term?
Thanks for your help.
