A Settling Ellipsoid
![[Animation]](1.jpg)
An ellipsoid sediments in a narrow vertical channel with rectangular cross
section containing an incompressible viscous fluid.
- the dimension of computational domain = (0,1)x(0,0.25)x(0,4), then it moves with
the center of the ellipsoid.
- the density of ellipsoid = 1.25.
- the density of fluid = 1.
- the viscosity = 0.01.
- the mesh size for the velocity field = 1/64.
- the mesh size for the pressure = 1/32.
- the time step=0.001.
