Matching fluid and structure meshes for aeroelastic computations : a parallel approach

Abstract Matcher is a program that generates the data structures needed for handling arbitrary and non-conforming fluid/structure interfaces in aeroelastic computations. In this paper, we describe the key issues addressed by Matcher and overview the underlying parallel algorithm. We highlight its parallel performance on the iPSC860/32 for a complete aircraft configuration where the fluid mesh contains 439,272 tetrahedra and 77,279 vertices and the structural model contains 7520 triangular shell elements and 3841 nodes.
