| Feb 20, 2023 at 1:46 | comment | added | ConvexHull | @WolfgangBangerth Sure, as a first step however, it should be sufficient to understand things like connectivity, orientation and lists. In FEM codes the ordering is rather element and side based and not node based. Further stuff, like spacefilling curves, MPI related things, BC handling or mappings for element to side or element to element, are of course missing. | |

The former you can find in many books on the FEM, the latter is typically only described in the form of code you need to dig through. | |
