Good morning everyone,

for my MSc thesis I am using SU2 for shape optimization and I would like to use AMR to reduce computational time.

I tried to install pyAMG from INRIA but, as it was released only for Linux and MacOS, I could not install it in Windows 10.

Has anyone any information about how to install it or about other AMR tools which I can use?

I am not very practical about compilers and whatsoever related so any help would be precious.

I tried to search information about this but I could not find any answer on the topic.

I am working with MATLAB and GMSH and I have found a tool which can be a solution but it will be last chance.

Thank you for your attention

Hi Andrea,


If you are working with gmsh, then there are a number of python tools that you can use. With pygmsh you can first try to create your current mesh. You can then read the paraview solution, and identify the cells that you would like to refine (I did this with pyvista). If you have the coordinates of the cells, you can then add these as refinement areas to the gmsh setup and remesh and save to su2.



Alternatively, you keep all the existing mesh points, and add the cell centers to the list, and then recompute the connectivity in gmsh. This latter method works in 2D for Delaunay triangulation, not sure if you can do this in gmsh in 3D.

Thank you very much for your reply!

I will try it and I hope to write a script to automate the process.
