[Gmsh] holes intersect boundary

[Nico Schlömer]

Hi,

I just played around with t5.geo which carves some ball-shaped holes
in a sample.
What I would like to do is to create some holes which may intersect
with the boundary such that, for example, a half-ball is cut out.
While it seems to be no problem to create the geo file, the 3D meshing
algorithm won't work: It only provides a mesh on the boundary if one
of the cavities intersects with the boundary.

Is there a workaround for this?

Cheers,
Nico
