Summary
Model geometry
We calculate a dam-break problem with three liquids: water, oil, and mercury, for 6 seconds. The calculation is performed as a two-dimensional problem with a single mesh in the Z direction.
The properties of each fluid are specified in the file "constant/transportProperties" as follows.

The interaction between the phases is also specified in the file "constant/transportProperties".
The meshes are as follows, and the number of mesh is 34200.

The calculation result is as follows.
The ID values of each fluid are as follows.
- Water: 0.0
- Oil: 1.0
- Mercury: 2.0
- Air: 3.0
