[Gmsh] question about python api

[Frederic Dubois]

Dear all, 

I am trying to mesh a composite material made of paste and grains. 
Since I have to do some Boolean operation on a 3D volume of composite I tried to use the occ factory. 
At the end of the day I need a continuous mesh where paste elements of the mesh belong to a paste physical group and grains elements belong to an other physical group. 

In the attached script I first create a cylinder and two grains. 
Using a cut I was able to obtain a mesh with all the elements belonging to the paste. 
Using a fuse I was able to obtain a mesh with all the elements belonging to the grains. 
Unfortunately, it seems that the two meshes are separated. 

I tried to fuse them to obtain a continuous mesh but I am not sure it works fine and that it is the proper method. 

Any advice ? 

Regards
