Hi! I'm modeling an open tank, using mutiphase model, phase1: air; phase2: non-newtonian fluid.

My problem is the flow throught the hole in the separating plate goes up to the top of the tank, like no gravity was set (in apparience).

I have checked a lot of settings and I think they are fine:

- Non-newtonian model activated and choosed
- Negative gravity on Y axis
- Pressure 1.73psig as boundary condition on inlet
- Pressure 0psig as boundary condition on outlet
- Pressure 0psig as boundary condition on ambient (top of tank)
- Air density 1225 kg/m3 as Operation Condition
- Patching in bottom region of tank, liquid fraction volume = 1
- 900 iterations was executed
- When i try modeling water as Phase 1, results appear to be correct (fluid goes up to the bottom oulet).

I will be grateful if someone can help to find the cause of error.
Thanks!

Solved, missing phase asignation to phase 2. Thanks.
