A multilevel method applied to the numerical simulation of two-dimensional incompressible flows past obstacles at high Reynolds number
Numerical simulation of turbulent flows in complex geometries is one of the most investigated fields in computer science in the last decades. But even though the power of supercomputers has regularly increased for many years, it has been understood that the numerical simulation of realistic flows at high Reynolds number would require too many efforts in term of memory and CPU time if one discretizes directly the Navier-Stokes equation.
