sahmed is on a distinguished road
I am simulating a flow through a tube with detailed chemistry, that means solving species conservation as well. For the outlet of the tube, I need a flow happening. If I use ZEROGRADIENT boundary condition at the outlet, it would be an insulated condition. Could anyone tell me which boundary condition at the outlet is appropriate for this condition for species, pressure, velocity and temperature?
