I am recently working on simulating a square dropping into water, here is the Youtube tutorial http://www.youtube.com/watch?v=fVzO2iQmbNQ
It is fine using Fluent 6.3
however, when using Ansys 14.0, it gets very strange result:
When the square approaches the surface, the surface concave down(as if pressed by the zone moving-fluid, not only moving-walls).
When the square is in the water, oscilation occurs and water begins to explode...
I still want to use 14.0, is there anyone who can help me on this issue?
