MESH_BASE_ONE:
  The element indexing appears to be 1-based!
  No conversion is necessary.

  ALPHA compares the smallest angle against 60 degrees.
  Values of ALPHA range from 0 (extremely poor) to 1 (excellent).

  ALPHA_MIN  : minimum over all triangles = 0.750000  45.000000
  ALPHA_AVE  : average over all triangles = 0.750000  45.000000
  ALPHA_AREA : average weighted by area   = 0.750000  45.000000

  AREA compares the areas of the triangles.
  Values of AREA_RATIO range from 0 (extremely poor) to 1 (excellent).

  AREA_MIN   : minimum area         = 0.500000
  AREA_MAX   : maximum area         = 0.500000
  AREA_RATIO : minimum/maximum area = 1.000000
  AREA_AVE   : average area         = 0.500000
  AREA_STD   : standard deviation   = 0.000000
  AREA_NEG   : area < neg           = 0
  AREA_ZERO  : area = 0             = 0

  Q is the ratio of 2 * inradius to outradius.
  Values of Q range from 0 (extremely poor) to 1 (excellent).

  Q_MIN  : minimum Q                  = 0.828427
  Q_MAX  : maximum Q                  = 0.828427
  Q_AVE  : average Q                  = 0.828427
  Q_AREA : average Q weighted by area = 0.828427

  The geometric bandwidth          M = 11
