What makes a good computational grid?
Most computational methods for solving PDEs are grid-based. What makes a computational grid "good", other than being sufficiently fine to resolve features of numerical solutions? … Is there a high-level overview, a paper or a book, discussing what makes a grid "good", for a range of solution methods and numerical problems of interest? …
