A front tracking algorithm for limited mass diffusion
The advantage of front tracking over capturing methods for the numerical simulation of discontinuity surfaces in fluid flow is to eliminate the numerical diffusion of mass across a fluid interface. For accurate modeling of an interface between miscible fluids, however, physical mass diffusion may be significant, and must be added to the calculation. The main purpose of this paper is to introduc...
متن کاملAn Algorithm for Eulerian Front Tracking for Solid Deformation
An attractive approach for simulation of large deformation solid dynamics is to combine Eulerian nite diierencing with material interface tracking. The Eulerian computational mesh is not subject to mesh distortion, and tracking eliminates spurious numerical diiusion at interfaces and the need for mixed-material computational cells. We have developed such an approach within the framework of the ...
متن کاملThree-Dimensional Front Tracking
We describe a three dimensional front tracking algorithm, discuss its numerical implementation, and present studies to validate the correctness of this approach. Based on the results of the two dimensional computations, we expect three dimensional front tracking to improve signiicantly computational eeciencies for problems dominated by discontinu-ities. In some cases, for which the interface co...
متن کاملSimple Front Tracking
A new and simplified front tracking algorithm has been developed as an aspect of the extension of this algorithm to three dimensions. Here we emphasize two main results: (1) a simplified description of the microtopology of the interface, based on interface crossings with cell block edges, and (2) an improved algorithm for the interaction of a tracked contact discontinuity with an untracked shoc...
متن کاملMultimaterial Front Tracking
We present the first triangle mesh-based technique for tracking the evolution of general three-dimensional multimaterial interfaces undergoing complex topology changes induced by deformations and collisions. Our core representation is a non-manifold triangle surface mesh with material labels assigned to each half-face to distinguish volumetric regions. We advect the vertices of the mesh in a La...
