WebApr 1, 1999 · Front tracking is a computational method in which interfaces or embedded geometrical surfaces are given explicit computational degrees of freedom. It is thus a hybrid method, mixing CFD with computational geometry. The authors consider here three applications of Front Tracking to the computations of dynamically evolving surfaces. … WebJul 25, 2006 · We describe a three-dimensional front tracking algorithm, discuss its numerical implementation, and present studies to validate the correctness of this approach.
Webmore details about the front tracking method. The main advantages of the front tracking method, is that the method is super fast [11], and preserves the frontal structure of the solutions extremely well. On the other hand, since the method heavily depends on solving Rlemann problems, it is not easy to extend the method to three-phase flow.
