Dynamic Mesh (3D) Sedimentation of a Rigid sphere
 

I'm working on a 3D problem concerning a rigid sphere falling into a rectangular container with a fluid - Water (for now). Somehow the ball doesn't seem to be moving. If possible please guide me through the process (right from meshing) or suggest a tutorial webpage on the same.

Thank you

im studying on a same model. sedimentation of rigid sphere depends on density in a rectengular tank. (sorry for my english). i need model and setup in fluent. can u help with it? (if u now the solution)

by the way, sphere will be inside the water tank already, when i will release it free , it will start to fall depends density
