simulation of free surface of stirred tank using vof

Jamal,
I am now working in the area of gas entrainment in stirred tanks. I had done the steps that you followed. While taking the contour of volume fraction before running, impeller and baffle walls are also coming in the phases. How I have to separate these parts from phases??

Hello everyone,

I am still very new to this topic and have a question . I want to simulate a stirrer which is half filled with water . The motion is not the problem. However, I don't get the visualization of the free surface.
I set the Volume fraction to Components (Water = Value 1.0 / Air = Value 0.0). I have tried to define the water level about position, volume and a lot more things, but nothing works.

What am I doing wrong?

The 2D Tutorial about Gravity driven Flow worked well. And I think I should also use a field function with the 3D simulation.

If you need more details, please let me know.

Thanks a lot!

Amelie
