I would recommend using the default one. (Is the quality of the STL meshes sufficient, or do you need to remesh them?) > What about optimization algorithms?

We will introduce some fine-tuning in the future to change the speed/quality tradeoff ; currently a good compromise is hardcoded. > > I would also like to suggest 2 improvements for future Gmsh versions: > > 1.

The official Linux binaries are compiled on the "old-stable" Debian, in order to support even quite old Linux distributions. Can you share the error you get on CentOS 6 ? > > 2.

Yes, that's indeed in our plans for a future revision of the MSH4 format, together with even better handling of very large meshes/datasets.
