A Parallel Boundary Conforming Method on Adaptive Moving Meshes for Multiphase Flows
… two-dimensional incompressible flows on adaptive moving unstructured meshes. The proposed method is especially helpful for studying immiscible multiphase flow problems as the interfaces are represented explicitly by mesh lines, and the grids are able to conform the movements of the interfaces. The …

Mesh generation for implicit geometries
… new techniques for generation of unstructured meshes for geometries specified by implicit functions. An initial mesh is iteratively improved by solving for a force equilibrium in the element edges, and the boundary nodes are projected using the implicit geometry definition. Our algorithm …

Modeling, analysis and numerical simulation of reactive solute transport problems in moving domains
… adsorption-desorption equation in moving domains. First, we present the mathematical formulation of the model in the arbitrary Lagrangian-Eulerian (ALE) framework. We study the well-posedness of the model.We then discretize the conservative variational form of the problem in the ALE …

A variational framework for multi-scale defect modeling in strained electronics and processing of composite materials
… The method is based on employing structured non-moving meshes to solve the Navier-Stokes equations employing a finite element method (FEM) stabilized via the Variational Multiscale Method (VMS). Within VMS framework a discontinuity capturing method is derived that allows for sharp discontinuity …

Development of an efficient 3-D CFD software to simulate and visualize the scavenging of a two-stroke engine
… geometry of the two-stroke engine with moving piston and rotating crankshaft. Due to the high temperature in the cylinder after combustion, a temperature dependent treatment of the material constants is necessary. <br>Adaptive local time-stepping and dynamic local mesh adaption, as well …
