Hello everyone,
I have a big problem with my modeling. I want to model some concrete block and see how it interact with water in the flume. I put GMO(and collision) & Viscous and turbulence & Gravity in physics of model. coefficient of friction=0.5 coefficient of restitution=0.53 Coupled motion with mass density=2000 (initial velocities=0) boundary condition: y min & y max & z min = wall , z max = symmetry , x min= wave , x max = wall. but blocks move and behave unreasonable as you can see in attached image, the blocks immerge together!!! how can I solve this problem?please help me?

Did you try smaller cells in your mesh?

Hi,
yes, as you seen at those picture, it is very fine mesh. This problem is not related to the mesh. |

Are the small blocks separated from the big block? Did you try placing them further away before starting the simulation?

have you ever use restitution coefficient 1?
