| Jan 17 at 4:25 | comment | added | helloworld922 | I would agree that Runge's phenomenon can reduce the order of convergence especially for high order multi-dimensional FD. I don't think it would prevent overall convergence, though (at least with exact real mathematics, not sure when you introduce floating points). | |
