Hi,

Dimitris Menemenlis a écrit :

I've tried to run an experiment wich a resolution divided by 2 
horizontally and vertically, and I still had some velocities, even if 
after 50000s there were 7 order of magnitude smaller than before. But if 
you wait enough, you always get some huge velocities, and everything 
mixed up.

Do you have any clues about why it doesn't blow up with the non 
hydrostatic approximation?
