[Gmsh] Fwd: problems about mesh characteristic length

[徐庶]

Dear gmsh developers:
     I sent you the following email three days ago, questioning about the
mesh characteristic length. Unfortunately, I haven't got your answers yet.
Would you please spend some time doing me this favor? thank you!
     Looking forward to your suggestion.

Best wishes
Shu

Dear authors:
        I'm a Chinese student and  recently meet some troubles when using
gmsh.
        1. In the gmsh manual, you mentioned the characteristic length of a
point will set the characteristic mesh length at that point. Can you give me
some more exact explantion about this, for instance, mesh characteristic
length represents what when I generate mesh? Is there any appropiate way to
determin this parameter before generating a geo module? Is the parameter
"Ic" the same thing with the characteristic length?
        2. In the "frequently asked questions" part, question 5.13, you
simplely interpret three parameters: Rho, Eta and Gamma, which I'm still not
clear. Unfortunately, I can't search out Geo/MElement.cpp in the manual. can
you send me the Geo/MElement.cpp or make some illustration about them, and
show me how to measure quality of the tetrahedra from these three
parameters? thank you for your patience.
        I'm a mesh novice and will appreciate very much if I can get some
favor from you. Looking forward to your suggestion!

Best regards
Shu
