Parallel Algorithm for Fully Nonlinear Aeroelastic Analysis Conference Paper uri icon

abstract

  • This paper presents the development of a parallel algorithm for a fully nonlinear aeroelastic analysis. The aeroelastic model consists of: (1) a nonlinear structural model that captures in-plane, out-of-plane, and torsional couplings, (2) an unsteady, viscous aerodynamic model that captures compressible flow effects for transonic flows with shock/boundary layer interaction, and (3) a solution methodology that assures synchronous interaction between the nonlinear structure and fluid flow, including a consistent geometric interface between the highly-deforming structure and flow field. A parallel computation algorithm based on message-passing interface was developed for the flow solver. This parallel computation algorithm and the grid generator of the flow solver were developed concurrently to improve the efficiency of parallel computation. Results are presented for the (original) Goland Wing and for the Heavy Goland Wing, for Mach numbers ranging from 0.09 to 0.7.
