Hi,
I am simulating mixing of two fluids of different viscosity and different density. For this I have defined a variable composition mixture. The domain is initially filled with fluid A( by defining mass fraction of A as 1 in the mixture initially). The fluid entering the domain is entirely composed of fluid B( by defining mass fraction of B as 1 at the inlet). Bouyancy is switched on to capture the hydrostatic effects. A transient simulation was done with total time equal to the time taken to travese the domain(at a fixed flow rate) The problem is that there is no flow at all. Instead a small portion of the fluid at the outlet comes in. I dont know why this happens. Would greatly appreciate any help Ranjith |

Did you initialize the hydrostatic pressure?

Domain Initialization. Read the tutorials on free surface flows to see how to initialize a hydrostatic pressure.
