Simon Guest Posts: n/a	I am simulating a simple diffusion flame. I am using a 2D square mesh. One side of the square is the two inlets (fuel stream in the center, the rest is the oxidizer stream) and the opoosite side is the outlet. The velocities of the streams are O(cm/s). The problem is that I don't get a converged solution, because I keep getting inflows at the outlet boundary, along with recilculation regions. Could the boundary conditions be faulty? Any suggestions are more than welcome.
