[Gmsh] How to draw Quad tree in Gmsh?

lzk12520 · January 3, 2016, 12:42

Is there a convenient way to draw quad tree mesh by Gmsh?

I browsed the function buttons and found no relevant option.

My goal is just to install a cylinder surrounded by O-grid into Cartesian grids, as my solver requires low aspect ratio and internal angle of grids. Should I just go to other software like Ansys mesh tools?

Grateful for any suggestion

As far as I can see, there is no quadtree mesh generation algorithm in gmsh https://gmsh.info/doc/texinfo/gmsh.h...ured-algorithm and even the Ansys Help showed 0 results with a search for "quadtree".
