<P><FONT face=Arial size=2>Hi,</FONT> </P>
<P><FONT face=Arial size=2>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).</FONT></P>
