... with separately. 5.1.1 Immersed bodies with elastic boundaries This is the class of flow problems Peskin had in mind when he developed the first IBMs [21]. His method solves the Navier- Stokes equations ... any stiffness parameter (as is the case in the continuous forcing methods), and that is of course good news. But the repeated use of the smoothed distribution function...
