Hello,
I have a question about the stability criterion in ROMS. I have found that there is a CFL criterion which is calculate with 2D time step like :

CFL = sqrt(gh)*Delta_t2d*sqrt(Delta_x^-2+Delta_y^-2)

And this CFL has to be lower than 1/2. But is there a stability criterion which is calculated with 3D time step? If yes, what is it's formulation?

Thanks
