Hi Isabela,

I would suggest you download the latest version of Gmsh (3.0.+) which has access to the OpenCascade factory. It is much more powerful at handling boolean operations (intersections, unions, etc.), have a look at the examples in this folder : http://gitlab.onelab.info/gmsh/gmsh/tree/master/demos/boolean.

Faithfully yours,

Objet : [Gmsh] Combination of volumes

Hi everybody!

I would like to know if it is possible to combine volumes. I have two cylinders created using the Extrude command. This cylinders intersect anyway, not sharing a surface but overlapping. Also this cylinder then will be holes in a box. So I am trying to combine a couple of cylinders (in the future there will be many many cylinders) and then subtract them from the box. I know the file here doesn't work since the volumes are overlapping.

Any ideas?
