Hi Bernhard - It's a recurrent problem with the old isotropic algorithm,
when some features are much smaller that the overall size of the
geometry. Reducing the random perturbation factor (gmsh -rand xxx) might
The thing I don't understand is why the new algorithm also (silently)
fails on this geometry. I tried to see why a couple of weeks ago, but
couldn't. I will have another look when I get a chance.
