Hello,

I am new to CFD and Ansys Fluent. I am using Ansys 2024R2 Student Version and I am interested in Multiphase Flow Analysis.

I am trying to follow this Youtube tutorial, but I dont obtain the same result. I dont get any useful result at all.

The following images are supposed to show the iso-surface of the water phase volume fraction = 0.

This is frame 19 from the solution animation:

This is the next frame, where water suddenly appears in all edges:

And this is frame 56 with water all over:

The only difference i notice between the tutorial and my case is the automatic adaption interface in my 2024 version, which looks quite different to the older version used in the tutorial. I checked Ansys User's Guide Chapter 38: Adapting the Mesh and think my settings are adequately enough, but I guess the error is there, so I will show my setting below.

Automatic Mesh Adaption settings with Refinement/Coarsening Criterions

Any hints to where I need to look at to get reasonable results are appreciated.
Thanks in advance.
