So based on the videos am I to understand that the cell values are independent?
In RF2013, it was recommended not to make the cell size of the objects lower than the domain but following the videos on luis's blog I tried out a few things and found that if you set the iso surface too low the fluid goes right through it like it wasn't even there.

My global cell size is set to .35

hybrido .3
object .05 goes through....

but hybrido .1
object .05 it appears fine

hybrido .1
object .02 goes through..

hybrido .09
object .02 fine

The other thing I noticed is that regardless of the object, in my case using a simple cross, no matter how small I make the cell size, I don't get any sharp corners to match the shape, so when I go to mesh I get penetrating geometry. So maybe increasing the offset might help...

How is the iso surface being calculated?

Hey,

If you watched the videos you saw the less cell size for objects was possible when using the objects in Shell mode. When they are using the Solid inside, it is not advisable to reduce the cell size with a less value that the hybrido has.

Any value you are applying to the global cell size or the surface offset parameter for your object will be modifying the isosurface mesh for it.
