If I had to do that, I would create the elementary triangle (of the “coarse” mesh if you want), then rotate it, and glue it 6 times… This surely won’t have the D\_6 symmetry, but I guess if you do it now with equilateral triangles 12 times your mesh should be invariant under the D\_6 group.  
Otherwise did you look at this [thread](https://community.freefem.org/t/how-to-build-a-structured-mesh/2175)?  
Hope this helps
