[Gmsh] lower limit for characteristic length

[Zenker, Dr. Matthias]

Hi there,
 
the question remains: is there a lower limit for the characteristic
length cl, and why does gmsh crash when some points have a small cl?
I would like to add another one: Is it possible that gmsh ignores the cl
of the control points of a spline except for the first and last one? If
so, is there a way to force gmsh to take into account the cl of the
intermediate points also?
 
Best regards, 
 
Matthias

	I was wrong, it crashes also for cl=0.0005 (but after a looong
time, and with a runtime error).

		Hi, 

		I wonder if there is a lower limit for the
characteristic length. I have a rather simple 2D geometry, and if I set
the cl for just two points to 0.0001, gmsh crashes during the meshing
after having given the error message "3 identical points in Qtest". The
.gmsh-errors file is not written. With cl=0.0005, this does not happen
(but it takes veeery long to compute the mesh).

		Best regards, 

		Matthias
