CFD ANSYS FLUENT simulation dragonfly hovering ISO SS

Isosurface of swirling strength around insect body. It shows detachment of vortices.

Numerical analysis of four-winged insect flight.
The dragonfly Juncea Aeshna was selected as a representative of the flying four-winged insect family for simulation study. In Catia software a geometric model is developed based on photos of the Juncea Aeshna dragonfly. Then this model is imported to Gambit software which generates a mesh for the purpose of numerical calculations. Elements of the mesh are fine around the space in which the wings move. Numerical calculations in three dimensional space are realized in the Fluent software. CFD calculations of insect flight are performed to adequately simulate flight in hovering mode.

Research is performed in Warsaw University of Technology - The Faculty of Power and Aeronautical Engineering - Institute of Aeronautics and Applied Mechanics.

Very cool. How did u manage do couple Catia and Fluent? I am more from the structural side

Your model is very good especially the way the iso surfaces have been displayed. It seems to be very accurate to actual insect flight wing motion.
