Front tracking method方法
Webfront tracking methods, a fixed uniform Eulerian Cartesian mesh is used for solving the fluid flow, and adaptive unstructured grid markers are used for tracking the phase-interface front. In the new algorithm, an adaptive anisotropic unstructured mesh is used for solving the fluid flow, as well as for tracking the phase-interface front. http://mseas.mit.edu/publications/PDF/Petillo_etal_front_tracking_AUVs_OceansIEEE2015.pdf

WebThe 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. In Section 4, we will discuss WebLA-UR 99-3985 Hydrodynamic Methods Front Tracking in Two Space Dimensions 8 An important aspect of the front tracking method in two or more space dimensions is the description of the geometry of the discontinuity fronts. The following set of definitions describe the most common set of objects used in describing the collection of tracked …
