Two ellipsoids sediment side-by-side in a 2D-like channel filled with
an incompressible viscous fluid:
- the dimension of computational domain = (0,1)x(0,0.25)x(0,4) initially,
then it moves vertically with the center of the lower one
- Three semi-axes are 0.1, 0.1 and 0.18.
- the density of ellipsoids = 1.1
- the density of fluid = 1
- the viscosity = 0.01
- the mesh size for the velocity field = 1/112
- the mesh size for the pressure = 1/66
- the time step=0.001
- The averaged speed is 1.659 for the last five periods.
- The averaged particle Reynolds number is 59.724 based on
the length of the longest axis (which is 0.36).
