Some simulation results at high Re †

A falling object at Re=800 †

• with volume rendering visualization of magnitudes of fluid velocity (=abs(vx,vy,vz))

• with visualization of fluid velocity on a central plane as vectors

• without visualization of fluid

• 128 x 128 x 256 grids x 200,000 steps => 4 hours on 6 core intel CPU.

• The size of falling body is 40 (L) x 16 (W) x 4 (D) in the unit of CFD grid.

• The density of falling body is 1.5 times heavier than the fluid.
