Hi Sumit,

what is the Reynolds number of the case you are trying to simulate?
Since the instabilities probably arise from a high Reynolds number you could try to apply a turbulence model. You can have a look at the aorta3D example where a Smagorinsky turbulence model is applied. This should allow for bigger timesteps or a coarser resolution.
