[Gmsh] R: problems (with opencascade?)

I'm sure there can be "better" ways to build the same geometry; if you had the time for example to show me how you'd generate the geometry of the case at hand I would be grateful.

In part this is also due to other issues that I found (for example this is the reason why the circles in the geometry were generated by first rotating/translating the points, instead of rotating/translating surfaces).

Your geometry construction seems a bit convoluted... And indeed to create duplicate curves on the boundary of the surfaces.

Quick fix: just "fragment" everything at the end, which will remove the duplicates:

s() = Surface "*";
BooleanFragments{ Surface{s()}; Delete; }{}
