Q-Morph: an unstructured quadrilateral mesh generator embedded in gmsh.
Hello everybody,
Some months ago, I have implemented the Q-Morph algorithm and included it in gmsh. I wrote the code very quickly. So it can further be improved/optimized, but hexaedral meshes (obtained by extrusion of quad mesh surfaces) provided by this code have already been used very succesfully for fluid-flow modelling, dispersion... with OpenFOAM and Code-Saturne. I am currently implementing the H-Morph algorithm to get a fully unstructured automatic hexaedral mesh generator embedded in this very good and famous tool: gmsh. Work will be finished in few weeks. The code I've written is under GPL, but I can't distribute the sources, because I did this work for a private company. However, I wanted to have public opinion about potential interests. Time is missing to do again the work for free, but I would be able to do all the work (Q-Morph + H-Morph) in about 3 months. Here are links to videos showing some of the capabilities of this new gmsh module: http://www.youtube.com/watch?v=8WLlrB6KS0Q http://www.youtube.com/watch?v=gWFtsijR1v0 http://www.youtube.com/watch?v=nL3OwoTfK50 http://www.youtube.com/watch?v=BM7cNgA-A8g http://www.youtube.com/watch?v=UrNLxpogIqk Please, let me know your opinion/questions/suggestions... Sincerely, JB |
I would love to see a function like this in gmsh. However, after March I probably won't have a need for this anymore. Maybe in the future.

I would love to find a job where I could spend all my time to develop this kind of numerical tools :)
Some news: - now the Q-Morph module is able to mesh topo, - H-Morph is almost finished. See the pictures in my albums. There is a small probability for the sources being freely available... but I don't know when... may be in years... it depends on my boss. |
Very interesting!
Hi jbf,
I was very impressed by the videos (especially #3 and #4, and I appreciated that you were showing the limitations in #5) and think this feature would be very, very useful and appreciated by many gmsh users. Personally, I'd also use this heavily. Currently, we have to pay a lot for a license of ANSYS (we're a small research centre, and even for those they cost a lot). The main reason is the quad/hexa meshing (the solver is actually pretty bad, so for high performance, we use external solvers). This thread is about half a year old now, do you have any updates?

Hi JB and Sebastian,
Any update on Q Mesh in gmsh ? Considering the videos are down, I guess the product has gone commercial, which would be sad.... What is the status ?? Thanks |
