[Gmsh] Characteristic length - svn vs gmsh 2.5.0

[Romain Quey]

Dear Gmsh developers,

I have a problem with the latest svn, which apparently does not handle
characteristic lengths in the same way than the stable release (2.5.0).

Attached is the example of a square defined by 8 points (4 at the
vertices and 4 at the middle of each edge).  All points have the same
value of characteristic length.

If I set it to 0.5, during meshing, the svn version adds nodes between
the points, whereas gmsh 2.5.0 does not (what I consider as normal
behaviour is not to).  Even if I increase the value of the
characteristic length, the svn version will always put an extra node
between the points, which is something I would like to avoid.

How come the svn version always put an extra node, and can it be
avoided?

Regards,

Romain
