A Semi-implicit Gradient Augmented Level Set Method
Here a semi-implicit formulation of the gradient augmented level set method is presented. The method is a hybrid Lagrangian–Eulerian method that may be easily applied in two or three dimensions. By tracking both the level set function and the gradient of the level set function, highly accurate descriptions of a moving interface can be formed. Stability is enhanced by the addition of a smoothing...

متن کاملA Local Semi-Implicit Level-Set Method for Interface Motion
This paper proposes and implements a novel hybrid level set method which combines the numerical efficiency of the local level set approach with the temporal stability afforded by a semi-implicit technique. By introducing an extraction/insertion algorithm into the local level set approach, we can accurately capture complicated behaviors such as interface separation and coalescence. This techniqu...
متن کاملAdaptive gradient-augmented level set method with multiresolution error estimation
A space-time adaptive scheme is presented for solving advection equations in two space dimensions. The gradient-augmented level set method using a semi-Lagrangian formulation with backward time integration is coupled with a point value multiresolution analysis using Her-mite interpolation. Thus locally refined dyadic spatial grids are introduced which are efficiently implemented with dynamic qu...
متن کاملA gradient-augmented level set method with an optimally local, coherent advection scheme
The level set approach represents surfaces implicitly, and advects them by evolving a level set function, which is numerically defined on an Eulerian grid. Here we present an approach that augments the level set function values by gradient information, and evolves both quantities in a fully coupled fashion. This maintains the coherence between function values and derivatives, while exploiting t...
