GEOS Adding features to `mesh

Adding features to `mesh_doctor`

Open TotoGaz opened this issue 2 years ago • 0 comments

Let's add new checks to mesh_doctor!

First batch of features done in https://github.com/GEOS-DEV/GEOS/issues/2274 :

[x] Check that all the elements of the mesh are supported (including that polyhedra can be converted into supported elements).
[x] Warn about "non-conformal" elements (in the sense that two close facing elements should not be shifted).
[x] Allow reordering of support nodes for the elements. A right-hand left-hand rule could be fixed easily.
[x] Checks that the polyhedra have their normals directed outwards. (not exposed through the CLI though)

More checkes:

[x] https://github.com/GEOS-DEV/GEOS/issues/2857
[ ] Improve the collocated_nodes feature so it handles the fractures as well (the nodes aside the fracture are legitimately colocated, but it creates noise that prevents from finding real issue).
[ ] Check that the fractured mesh is consistent (collocated nodes are really collocated)
[ ] Validate ranges of fields (e.g. density should be positive). Printing statistics for fields can be enough. Check for NaN. Check for connection numbers (can be useful since some arrays have a maximum size based on number of connections.)
[ ] Build some mesh statistics (cell types, cell sizes, number of cells sharing the same node, etc.)
[ ] Add a field manipulation feature that will (among other features) allow to grab one field from an output simulation into the input of another.
[ ] Try to find holes in the mesh.
[ ] Find isolated elements (unused points, disconnected cell...)
