A Fast Parallel GridFree Method for Simulating Turbulent Incompressible Flow In/Around TimeVarying Geometries Phase I SBIR Project Funded By NSF This Small Business Innovation Research Phase I project prepares the groundwork for the development of the first commercially available Computational Fluid Dynamics package for a truly gridfree Large Eddy Simulation (LES) of transitional and turbulent incompressible vortex dominated flow in complex timevarying geometries. The computational engine is based on the parallel, fast multipole implementation of a Lagrangian vortexboundary element method, and turbulence is accounted for via LES, using a Lagrangian dynamic Smagorinsky subgrid scale model. The method is


Wallbounded turbulent flow examples will be provided during Phase II of the project. Refer to the Gallery Section for some examples of our firstgeneration gridfree wallbounded flow capability.
