Verification & Validation

1. Perform additional runs with timesteps of 0.02 and 1s. Comment on the stability of the scheme relating to the timestep by comparing the residuals. 
2. Compare the residuals and the vorticity figures for a mesh of 128x64 or another mesh of your choosing. Is there any noticeable differences between the results using different mesh sizes?  

Effect of Uniform Initial Condition

In our simulation, we patched the cells behind the cylinder to have a starting velocity of .2 m/s so that we would get the vortex shedding earlier. This also allowed us to better see the oscilliation of the lift coefficient as flow time increased.
