VOF
 
Is there any difference between the followings:

1) In Gambit creating ONE zone, importing the grid by fluent, marking a zone and patching that zone as a fluid2 and rest fluid1 (for VOF calculation)

2) In gambit creating 2 different zones and patching these two zones.

There is no difference, you can use both methods.

But be careful. If you make a register to patch (a region), then fluent will take a number of cells. Your region to patch can have a very strange shape if you have an unstructured mesh, or if the mesh does not follow the shape af the region you want to patch.

In a rectangular 2D-mesh, you cannot make a smooth circular region.

If this is of concern: use your second option.
