  1. Fluid-Structure Interaction Using Unstructured Meshes Small Business Innovation Research Fluent, Inc. Lebanon, NH INNOVATION Unified treatment of fluid-structure interaction solving solid and fluid regions in one sweep • ACCOMPLISHMENTS • Developed and tested robust and accurate schemes for computing flow on moving and deforming unstructured meshes • Coupled a code for structural computation (both deform- able bodies and rigid bodies with spring-mass-damper) to the code for fluid flow analysis • COMMERCIALIZATION • Integrated the code developed under this SBIR as an important part of a general purpose CFD code • Marketing and selling this general purpose CFD code under the name FIDAP • Broad commercial application of FIDAP includes turbo- machinery, automotive, chemical processing, material processing, biomedical, and offshore industries Deflection of Flexible Structure Behind Rigid Bluff Body • GOVERNMENT/SCIENCE APPLICATIONS • Useful to both NASA and the military in fluid-structure interaction problems in turbomachinery and in flexible and rotary wings 1993 Phase II, NAS3-27637, 12/01 NASA Contact – Nan-Suey Liu Company Contact – Stefano S. Mereu Glenn Research Center Aeronautics 3-075
