Hi, I'm trying to simulate temperature stratification of water inside a tank, via transient simulation. THe initial temperature of the fluid inside the tank is 35 °C and the inlet (Mass-flow inlet) flow has a temperature of 41.3 °C. The output is placed on the cilindrical wall, perpendicular to the ground. I set the output as pressure outlet.
My problem is that I can't remove the reversed flow on the pressure outlet. Morevoer the temperature in the tank takes too much physical time to reach the expected value.

I'm using a pressure based solver with a k-epsilon turbulent model.

Hope that somebody has some good ideas.
Thanks everybdoy
