[Gmsh] Meshing algorithms and suggestions

[Guilherme Saturnino]

Dear Gmsh developers,

I'm working on a package called SimNIBS (http://simnibs.org/) that does 
FEM simulations in human head models. We use gmsh to create tetrahedral 
meshes from stl surfaces of brain and other tissues. Is there any 
particular meshing algorithm you would suggest for this application? 
What about optimization algorithms? We prefer robustness and quality 
over speed.

I would also like to suggest 2 improvements for future Gmsh versions:

1. Is it possible to provide Gmsh 4 binaries that are compatible with 
CentOS 6? It is an old but still widely used Linux distribution. This 
has been holding us back in adopting Gmsh 4.

2. Would it be possible in future releases to have more flexible data 
types in $NodeData and $ElementNodeData? I think it would be very useful 
to store single-precision floats (to save space) or integers (to have 
additional labels for elements and nodes) .


Thanks a lot for putting so much time and effort into making this great 
piece of software.


Best Regards,

Guilherme Saturnino
