Rearchitecture of the ghosting setup

[TotoGaz]

In order to allow the import of

• wells and EDFMs,
• on top of the DFN and the main 3d mesh,
• while managing all their interactions,

we need to reorganize the ghosting setup strategy of geos.

Here’s a list of the main actions items

Theoretical background

• [x] Global numbering techniques
• [x] Parallel adjacency matrix
• [x] Regular presentations to the team
• [x] Handover to Ryan
• [ ] Improving the algorithm (how many times do we have to do upward/downward multiplication? Can we merge upwards and downward matrix?)

Implementation

• [x] Global numbering techniques
• [x] Parallel adjacency matrix
• [ ] Plug into current GEOS (find the best way to bring the feature).
  • [x] Make it available for the "general case"
  • [ ] Handle Fracture
  • [ ] Handle wells (if required)
  • [ ] Handle particle methods
  • [ ] Handle high-order methods
  • [ ] Handle the InternalMeshGenerator
  • [ ] Handle multiple cell types
  • [ ] Temporary indicator to use new/old ghosting
  • [ ] Hook up to use/create globalIDs
  • [ ] Finish tpetra conversion (hard coded matrix sizes)
• [ ] Trilinos use and possibility of using LAI + LvArray
• [ ] GEOS packing
• [ ] Typed integer use
• [ ] Cleaning implementation
• [ ] Remove obsolete code
