Detailed Description

Reorder_Mesh allows the user to trigger the renumbering of the mesh entities.

!

Renumbering can be done according to a Morton or Hilbert scheme (see Morton curve or Hilbert curves on Wikipedia) thus improving the data co-localisation, in the following sense:

  • when iterating through the faces of the mesh
  • and then retrieving the adjacent elements (indirection via face_voisin typically)
  • ensures that the elements that are thus scanned are themselves not too wide spread in memory

This helps improving memory access performance. See .cpp file for more explanations on how this works.

This object is used as a discretisation option - see class Discret_Thyd, member reorder_
