motion for a front propagating with curvature-dependent speed. This equation is an initial-value Hamilton-Jacobi equation with right-hand side that depends on cur- vature effects. The limit of the right-hand side as the curvature effects go to zero is an eikonal equation with an associated entropy condition.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We devise new numerical algorithms, called PSC algorithms, for following fronts propagating with curvature-dependent speed. The speed may be an arbitrary function of curvature, and the front can also be passively advected by an underlying flow. These algorithms approximate the equations of .

Journal of Computational Physics, 79, pp. 12 . Fronts propagating with curvature dependent speed: algorithms based on Hamilton-Jacobi formulations. The need to follow fronts moving with curvature-dependent speed arises in the modeling of a wide class of physical phenomena, such as crystal growth, flame propagation and secondary oil recovery. In this paper, we show how to design numerical algorithms to follow a closed, non-intersecting hypersurface propagating along its normal vector field Cited by: 4. S. Osher and J. A.
