In this study a MIMD parallel numerical algorithm for computationally intensive bio-flow simulations has been proposed in the finite element framework. The segregated variable approach in conjunction with the domain decomposition strategy employed in the current parallel scheme is easy to implement, makes it amenable to handle complex bio-flow domains, and is less demanding on computational resources. The parallel method has been successfully tested in simulating hemodynamics in arteries with multiple aneurysms. Encouraging speedup and efficiency factors have been obtained in the parallel fem simulations.
