Hi folks, I'm modelling unsteady two-phase flow problems and was wondering if there was an (easy!) way of refining my grid in the area where, for instance, phase contours are steepest after a few time steps? This would enable me to get a better resolution of the phase interface. I know approximately where the grid needs refining and could do it manually in Gambit, but doesn't the adapt grid function in Fluent do this for you?

yeah in fluent go to adapt, then gradient, choose phase, compute what your gradients are then choose a level you want to refine to, mark to find out which cells will be refined, then manage...display to view those cells, when you are happy hit adapt.

The fluent manual gives better details

Thanks, that's exactly what I was after!
