ABSTRACT:
The added-mass instability has, for decades, plagued partitioned
fluid-structure interaction (FSI) simulations of incompressible flows
coupled to light solids and structures. Many current approaches require
tens or hundreds of expensive sub-iterations per time-step. In this talk
some new stable partitioned algorithms are described for coupling
incompressible flows with (1) compressible elastic bulk solids, (2) thin
structural beams and (3) rigid bodies. These added-mass partitioned (AMP)
schemes require no sub-iterations, can be made fully second- or
higher-order accurate, and remain stable even in the presence of strong
added-mass effects. These schemes are implemented using moving and
deforming overlapping grids with the Overture framework.HOST:  Jose Castillo
