An Adaptive Mesh Refinement Strategy for Immersed Boundary/Interface Methods.

An adaptive mesh refinement strategy is proposed in this paper for the Immersed Boundary and Immersed Interface methods for two-dimensional elliptic interface problems involving singular sources. The interface is represented by the zero level set of a Lipschitz function φ(x,y). Our adaptive mesh refinement is done within a small tube of |φ(x,y)|≤ δ with finer Cartesian meshes. The discrete line...

Adaptive Mesh Refinement Strategies for Immersed Boundary Methods

In the present study we propose an adaptive mesh refinement (AMR) strategy which can be coupled with embedded boundary methods in a straightforward manner. The building-block of the AMR solver is a structured Cartesian solver employed on a hierarchy of sub-grids. A fractional-step formulation is used for the time advancement, and all spatial derivatives are discretized on a staggered grid using...

Adaptive mesh refinement strategy for a nonconservative transport problem

In the framework of transport equations it is usual to need long time simulations, and therefore large physical domains to cover a phenomenon. On the other hand it can happen that only a small time varying portion of the domain is interesting. This motivates the use of adaptivity for the spatial discretization. Biological models involving cell development are often nonconservative to account fo...

Adaptive Methods for PDE ’ s Wavelets or Mesh Refinement ?

Adaptive mesh refinement techniques are nowadays an established and powerful tool for the numerical discretization of PDE’s. In recent years, wavelet bases have been proposed as an alternative to these techniques. The main motivation for the use of such bases in this context is their good performances in data compression and the approximation theoretic foundations which allow to analyze and opt...

plied and theoretical physics is to fully understand and predict the behavior of systems far from thermodynamic equilibrium,1–4 including those systems driven by an external force or experiencing a sudden change in environment (such as pressure or temperature). They also include systems transitioning from one metastable or long-lived state to another. The need to accurately model and numericall...
