The mesh and geometry for the two converging-diverging channel cases, corresponding to Reynolds numbers of ReH = 12,600 and 20,580. The Reynolds number for these two cases is based on the channel half height H and the maximum inlet velocity Umax. The ReH = 12,600 converging-diverging channel case uses a smaller domain than the ReH = 20,580 case, but with an identical mesh.
