摘要

针对反应扩散问题，提出了一种生成各向异性网格的方法。采用保守有限差分法对这些网格上的反应扩散问题进行离散化。我们将该方法与传统的均匀细化技术进行了比较，结果表明，对于具有各向异性解的问题，各向异性网格是理想的。

Mesh optimizatin : Anisotropic or Uniform Meshes for Reaction Diffusion Problems?

We present a method for generating anisotropic meshes for reaction diffusion problems. A conservative finite difference method is used for discretizing reaction diffusion problems on these meshes. We compare our approach with the traditional uniform refinement technique, and show that for problems with anisotropic solution, anisotropic meshes are ideal.
