Hi
First many thanks for this great tool!
But now I am stuck with the following problem. I want to create a 3D volume mesh from an imported stl surface. The surface doesn't self-intersect but the meshing was not successful. I tried different meshing algorithms but none did succeed. Now my question is what the failure in my stl surface could be that ceases gmsh from successful meshing.
I got the following error messages:

I am running Gmsh Version 2.4.2 on 64 bit Linux Ubuntu.
Any help is appreciated.
Many thanks!
