[Gmsh] CSG type operations.

[C.Stott]

Hey, 

I'm fairly sure this can't be done with gmsh at the moment, but I thought I would double check, and if it's not possible maybe figure out if it's possible to get it working / throw it open to the floor to see if anyone knows how I could do it. 

I'm trying to model an asymmetric curved bifurcation. The model is made up of 3 tubes: 1 straight and 2 curved. The curved ones overlap and bend in opposite directions, emerging from the straight pipe. The attached screengrab will hopefully help imagine it. 

Is there anyway I can get gmsh to mesh this? Is there some way to get it to take the union of the two curved pipes? Even getting the surface mesh would be fine. 

If it's not possible, is there any other software any one knows of that might work? One approach might be to get the surface mesh of the individual pipes, and find some software that can apply CSG operations to surface meshes, and mesh the result. 


Many thanks,
