| 335 ## Implementation of boundary_indices for more complex grids | |
| 336 To represent boundaries of for example tet-elements we can use a type `IndexCollection` to index a grid function directly. | |
| 337 | |
| 338 ```julia | |
| 339 I = IndexCollection(...) | |
| 340 v[I] | |
| 341 ``` | |

| 343 * This would impact how tensor grid works. | |
| 344 * To make things homogenous maybe these index collections should be used for the more simple grids too. | |
| 345 * The function `to_indices` from Base could be useful to implement for `IndexCollection` |
