2D or 3D
 

Dear all
Hi,
I just got a problem working with STAR-CCM+. My aim is to model falling of a 2D circle through the water. I am confused if I should choose a 3D model or 2D? because the problem is a 2D simulation by nature but if I choose 2D one I can not use 6-DOF.Is there any other option to do this simulation while I m using 6-DOF?
thanks a lot.

Hi,
6DOF can not provide the request of 2D simulation.
