Thanks for the suggestion, but I'm already using Linux.

I have a mesh that is a repeating lattice of unit cells. When I use a 
relatively small lattice, say 10x10, the mesh is always created without error. 
However, for larger lattices, say 25x25, I commonly get the error `Identical 
points in triangulation: increase element size or Mesh.RandomFactor`. I've 
looked at the documentation, and the ratio of my smallest element size to model 
size is 1e-3 at worst. Regardless, I've increased Mesh.RandomFactor to 1e-6 and 
I still get errors. I can't really increase my characteristic length any larger 
because it's already around the order of the smallest geometric feature. Does 
anyone have any other troubleshooting suggestions? I've attached my `geo` file 
in case it's helpful.
