WebThe threshold dynamics algorithm of Merriman, Bence, and Osher is only first order accurate in the two-phase setting. Its accuracy degrades further to half order in the multi-phase setting, a shortcoming it has in common with other related, more recent algorithms such as the equal surface tension version of the Voronoi implicit interface method. As a first, … WebThreshold Dynamics for Compartmental Epidemic Models in Periodic Environments Wendi Wang · Xiao-Qiang Zhao Received: 5 August 2007 / Published online: 23 April 2008 © …

Webenables it to achieve high order in space more easily. These advantages increase the appeal of our algorithm for certain applications in computational ﬂuid dynamics. Our scheme may be extended to handle topological changes and multiphase ﬂows such as wetting problems as in [30,32], but that is outside the scope of this paper. WebThe departure point is the threshold dynamics algorithm of Merriman, Bence, and Osher for the two-phase case. A new energetic interpretation of this algorithm allows us to extend it in a natural way to the case of N phases, for arbitrary surface tensions and … how to remove oil stains from white marble
