hi all.
I am a Beginner cfx user.I want to simulat a column that have two inlet and two outlet in up and downsid.liquids are kerosene and water. kerosene (dispersed phase) inject from down column and water (continues phase) inject from up.
taken k-e turbulence model for continues phase.
column diameter is (5 cm) and have (3.45 m) height.
used Ansys cfx 14.5
When solution after 1500 time step linear solution was falsed.
how i set solver parameters?

plz help me
