====Vorticity confinement method====

{{Main|Vorticity confinement}}

The [[vorticity confinement]] (VC) method is an Eulerian technique used in the simulation of turbulent wakes. It uses a solitary-wave like approach to produce a stable solution with no numerical spreading. VC can capture the small-scale features to within as few as 2 grid cells. Within these features, a nonlinear difference equation is solved as opposed to the [[finite difference equation]]. VC is similar to [[shock capturing methods]], where conservation laws are satisfied, so that the essential integral quantities are accurately computed.
