For me, since I've just tried GMSH, SnappyMesh, SALOME and from my limited experience, I can handle every kind of Mesh using either GMSH or SnappyMesh.
GMSH is used for a not very complicated models and it offers many functions for controlling the Mesh
SnappyMesh is used for more complicated models (but it is not really good for models which have high aspect ratio features). All i have to do is creating a .stl file by any CAD software.

ANSYS Meshing is really good. I think its GUI is unchallengeable.

I am new to OpenFOAM. What do mean by complicated models?

blockMesh + SnappyHexMesh. (Solidworks for creating the geometry)

The software seriously rocks when it comes to mesh generation! I have been using it for over a year now, and always keep it up to date from CVS....

So far... the only complaint I have is that it does not do a good job when there are long narrow gaps (for example concentric cylinders with gaps which are very small compared to the rest of the geometry).

Also... it can only create pure tetrahedral meshes in 3D (though, for my applications... this does not seem to be so much of a limitation)

As for importing into OpenFOAM... flawless.... Mesh Quality... very very acceptable.... Complexity.... hardly complex :-)..... Type of geometries it can handle... yet to find one which it cannot handle :-)!

It can directly import STEP and IGES files (if compiled with OpenCascade support)... and I dont need to do anything special when exporting out of Pro/E.

And on a purely personal note.... I have tried Gmsh and Tetgen... but found netgen to be much more user friendly... and the GUI easier to work with.

Which one is best for the small thin regions like the one you described above?

Furthermore, I have a technique now for generating "manifolds" from the Blender surface mesh, and using Calculix to create "columns" of hex between each manifold. To generate manifolds I first use a seperate Python script to project normals from the quad surface and make any manual adjustments needed, then export to Calculix. Exports from Calculix to OpenFOAM are without error.

If you'd like to learn this technique, I'd be happy to share my experience with you through this forum, so that others may also benefit. A formal tutorial is really needed, but for now some of my prior postings may be useful as an introduction to this technique.

BETA CAE systems, ANSA pre-processor.
All above solutions, they consume high amount of Memory and processing power of CPU for large model support. This one can perform computation on lower specifications of systems.

Ennova is a commercial pre- post- processor that can import, clean and repair CAD and generate tet + prism meshes or polyhedral meshes with boundary layers. It has a full GUI for setting up the openFOAM dictionaries and has post processing. Free for students ! Reasonable cost for commercial applications. Visit www.ennova-cfd.com. Thanks -Mike

Hi Mike,

I reached out to ennova-cfd via email 'info@ennova.tech' to request a student license for meshing software. I have not received any response them yet.
Would really like to use the meshing software which can generate better meshes for complex geometries such as burners and combustors.

And since I being in university as student, I would like to avail the opportunity of using the software created by the original creator of ICEM CFD software for 'less cost' to 'no cost' options.
