[Gmsh] characteristic length

[Ningfeng HUANG]

Hi there,

I found the characteristic length is rather intriguing.

I used the following code

Point(1) = {0, 0, 0, 0.1};
Extrude {1, 0, 0} {
     Point{1};
   }
Extrude {0, 1, 0} {
     Line{1};
   }

and GMSH gives three elements per side. See attachment. Should I expect 10
elements? or I misunderstood the definition?

Thanks in advance.

Peter
