Before revision:   In the process, we show the superiority of the proposed strategy over the EJIIM and other existing IIM methods .
After revision:  We also simulate a plethora of fluid flow problems past bluff bodies in complex flow situations, which are governed by the Navier-Stokes equations; they include problems involving multiple bodies immersed in the flow as well. In the process, we show the superiority of the proposed strategy over the EJIIM and other existing IIM methods .
