We present a parallel finite element computational method for 3D simulation
of fluid-structure interactions (FSI) in parachute systems. The how solver
is based on a stabilized finite element formulation applicable to problems
involving moving boundaries and governed by the Navier-Stokes equations of
incompressible flows. The structural dynamics (SD) solver is based on the
total Lagrangian description of motion, with cable and membrane elements. T
he nonlinear equation system is solved iteratively, with a segregated treat
ment of the fluid and SD equations. The large linear equation systems that
need to be solved at every nonlinear iteration are also solved iteratively.
The parallel implementation is accomplished using a message-passing progra
mming environment. As a test case, the method is applied to computation of
the equilibrium configuration of an anchored ram-air parachute placed in an
air stream. (C) 2000 Elsevier Science S.A. All rights reserved.
