Note, that the linear grids have been generated by DLR in the ADIGMA
project. However, the precision of grid coordinates have been further
increased.

The quartic grids have been generated by DLR based on the nodes given in the
rae2822_level*.msh files:
- The elements in rae2822_level5.m4.msh are curved based on the additional
  nodes given in rae2822_level4.msh and rae2822_level3.msh
- Analogously, the elements in rae2822_level4.m4.msh are curved based on the
  additional nodes given in rae2822_level3.msh and rae2822_level2.msh
- Analogously, the elements in rae2822_level3.m4.msh are curved based on the
  additional nodes given in rae2822_level2.msh and rae2822_level1.msh
- The elements in rae2822_level2.m4.msh are curved based on the curvature
  provided by rae2822_level3.m4.msh
- The elements in rae2822_level1.m4.msh are curved based on the curvature
  provided by rae2822_level2.m4.msh
As a result the geometry approximation in rae2822_level1.m4.msh is the same
as in rae2822_level3.m4.msh.
