Hi all,

I just had a quick look at the program, and there is one thing irritating me:

In adjustTimeStep(), the maximal fluid veocity is calculated. But for the
CFL-criterion the maximum of the SUM of fluid velocity and local sound speed
has to be used, AFAIK. Maybe this is not the case for incompressible situations,
so please correct me if I'm wrong.
