A parabolic level set reinitialisation method using a discontinuous Galerkin discretisation [figure data]

Thomas Adams, Nicholas McLeish, Stefano Giani & William M Coombs
Level set reinitialisation is a part of the level set methodology which allows one to generate, at any point during level set evolution, a level set function which is a signed distance function to its own zero isocontour. Whilst not in general a required condition, maintaining the level set function as a signed distance function is often desirable as it removes a known source of numerical instability. This paper presents a novel level set reinitialisation...
