In this course you will learn about hexa meshing of ONERA M6 wing.​

In first part we have made geometry of ONERA M6 wing in Solidworks and now same geometry will used for making the grid.

ONERA M6 is a classical test case for CFD validation. Although geometry is simple, but the flow field involves complex flow features such as transonic flow (Mach No. 0.7 - 0.92) with shocks, boundary layer separation etc. The ONERA M6 wing was designed in 1972 by the ONERA Aerodynamics Department as an expental geometry for studying three-dimensional, high Reynolds number flows. ONERA is a swept back wing, with half span. It is external third of M5 Wing without twist.

In this three part course series, you will learn about the conducting CFD analysis of ONERA M6 wing as per data given by AGARD AR 138 1979 by Schmitt, V. and F. Charpin.

Learning outcomes of this course
