Adaptive Meshes

Part of the Texts in Applied Mathematics book series (TAM, volume 15)

In Section 0.8, we demonstrated the possibility of dramatic improvements in approximation power resulting from adaptive meshes. In current computer simulations, meshes are often adapted to the solution either using a priori information regarding the problem being solved or a posteriori after an initial attempt at solution (Babuška et al. 1983 & 1986). The resulting meshes tend to be strongly graded in many important cases, no longer being simply modeled as quasi-uniform. Here we present some basic estimates that show that such meshes can be effective in approximating difficult problems.
