I think the PR really looks great! Thanks for your work. I have a last minor thing to fix (i.e. test should always be inside testsets to not leak any information) and if the CI does not fail, then things are fine from my side.

Sorry, I totally missed that tests for 3D are missing in the PR. Did we just discuss it in the comments/slack? Anyway, can you provide the test coverage for 3D grids? (Prism, Tet, Hex) I think we really can need the helpers in this PR for a full automated consistency check of interpolation implementations. :)
I also have a quick question on one of the tests.

We might be able to speed these functions up with code generators instead of passing the types and functions by hand. See e.g. https://github.com/Ferrite-FEM/Ferrite.jl/blob/master/src/Grid/grid.jl#L948-L961 . If it is too difficult to setup, then feel free to skip this comment. :)

I pushed some formatting changes and squashed. Also changed Thanks for the contribution, and sorry for the slow review! |
This patch adds `addboundaryfaceset!`, `addboundaryedgeset!`, `addboundaryvertexset!` for adding entities that are located on the boundary (defined as no cell neighbor). In addition, this adds internal functions for getting subentites from entities and various other helpers (`getfaceedges`, `getfacevertices`, `getedgevertices`, `getfaceinstances`, `getedgeinstances`, `getvertexinstances`, `filterfaces`, `filteredges`, `filtervertices`). Fixes Ferrite-FEM#595.

fixes #595 (
addboundaryfaceset!,addboundaryedgeset!,addboundaryvertexset!) and adds helper functions to get face/edge edges/vertices (getfaceedges,getfacevertices,getedgevertices).
