WitrynaImmersed boundary methods were first introduced by Peskin (1972) to simulate cardiac mechanics and associated blood flow. One distinguishing feature of this approach is the ability to perform the entire simulation on a fixed Cartesian grid. A novel procedure was developed by directly imposing the effect of the immersed boundary on the flow; the ... Witrynanumerous iterations for convergence as the multidirect forcing immersed boundary method [32,6]. Taira and Colonius [44] proposed the implicit immersed boundary projection method (IBPM) by formulating the boundary force and the pressure into a modiﬁed Poisson equation and solving them simultaneously in an enlarged system …
