Multiscale sequentially-coupled fsi computation in parachute modeling

Abstract

We describe how the spatially multiscale Sequentially-Coupled Fluid–Structure Interaction (SCFSI) techniques we have developed, specifically the “SCFSI M2C”, which is spatially multiscale for the structural mechanics part, can be used for increasing the accuracy of the membrane and cable structural mechanics solution in parachute FSI computations. The SCFSI M2C technique is used here in conjunction with the Stabilized Space–Time FSI (SSTFSI) technique, which was developed and improved over the years by the Team for Advanced Flow Simulation and Modeling (T AFSM) and serves as the core numerical technology, and a number of special parachute FSI techniques developed by the T AFSM in conjunction with the SSTFSI technique.
