Description of the flow problem
- Circular Domain of diameter 14.5
- Four heated circles of radius 1 each located at Xi =3.7123
and Yi=3.7123 and a heated blade located at the center(0,0). The width
of each blades are 0.56 units and length of 2.25units.
- inflow b.c.'s: Natural boundry conditions.
- outflow b.c.'s:NAtural Boundry conditions.
- Other b.c.'s: Non zero velocity at a diameter of 5 units
from the center.
- initial condition at t=0: starting from rest
- viscosity parameter: 1/nu=1,00,000

Description of the temporal discretization
- equidistant time stepping for computation with k=0.01
- equidistant time stepping for visualization with k=0.25 (=
1 frame)
- Total time T=30 corresponds to 3,000
time steps
- fractional step theta scheme
