I've searched the forum to read other experiences of GGI interfaces, but I couldn't find anything suitable.

I have a large complicated geometry. I can create large hexahedral areas, and backfill the rest of the volume with tetrahedral elements.

The catch is my mesh will be non-conformal: where the grid on either side of two connected surfaces will not match.

I've read GGI theory in the Ansys guide, and it seems promising.

Does any one have any simulation advice using GGI?

My particular simulation is a multiphase one, involving phase change at the free surface between two continuous fluids.

The obvious answer is to do a sensitivity study to see if anything is effected. But on top of that, does anyone have any advice?

Thank you.
