Two phases fluids in a tank
 

Hello,

I have a tank which I don't know the volume (because of a strange shape).

However, I want to fil my tank with 30 centimers of water and then fil the rest with oil as an initial condition.

How can I define such a thing in CFX-Pre ?

I have defined my tank as one domain and have defined two materials (oil and water).

Regards,

Hervé

Use the step function in a CEL expression for the initial conditions. See the bump tutorial for an example.
