Level set methods

Level set methods

Level sets are a powerful tool for the description of static or moving interfaces that are embedded into a background domain. Here, the location of the embedded interface is implicitly given by the zero iso-contour of a level set, which renders the approach generic and extremely flexible.

Circular Swirl Deformation

by: Dr.-Ing. Roozbeh Mousavi

Deformation of an eccentric circle in a periodic swirl velocity field. The period of deformation is 10. The grid resolution is 0.033333 and the DG order is 5.
