Fluid-Structure Interaction Using Unstructured Meshes

Fluent, Inc.

Lebanon, NH

Unified treatment of fluid-structure interaction solving solid and fluid regions in one sweep

• 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.

• 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.

• Useful to both NASA and the military in fluid-structure
  interaction problems in turbomachinery and in flexible and rotary wings
