[Gmsh] Gmsh High Order Element Problem

[Mikhail Artemyev]

Hi Kamil,

Basically, characteristic length is a length of a mesh edge (on a line 
connecting points where the characteristic length is defined). But you 
can find more information about it searching in Gmsh's mailing list 
archive http://geuz.org/pipermail/gmsh/

Best,
Mikhail
