**Parachute fluid-structure interactions: 3-D computation.**
*(English)*
Zbl 0973.76055

Summary: We present a parallel computational strategy for carrying out three-dimensional simulations of parachute fluid-structure interaction, and apply this strategy to a round parachute. The strategy uses a stabilized space-time finite element formulation for the fluid dynamics (FD), and a finite element formulation derived from the principle of virtual work for the structural dynamics (SD). The fluid-structure coupling is implemented over compatible surface meshes in the SD and FD meshes. Large deformations of the structure are handled in the FD mesh by using an automatic mesh moving scheme with remeshing as needed.
