I found that some Field Variable options (Derivative and Scaling Options) cause Fluent to instantly crash. I am currently getting some mesh adaption, but the CFL number exceeds 250. With the droplet boundary causing some unusual flame like results.

Any recommendation as what ‘Minimum Edge Length’ or ‘CellVolume’ (I have a 2D case) should be?

Finally, when I try to use Model: LES (currently using SST K-Omega with mesh adaption), none of the options for mesh adaptation work.  Causing an instant crash. I am aware that SST k-omega is the preferred model for VOF/Multi-Fluid VOF applications. 

Cheers!
