Hi Daniel,

examples/diffusion/circle.py executes cleanly for me, with FiPy 
3.1-dev131-g77851ef and Gmsh 2.11.0.

This looks like an installation problem. The up-to-date FiPy codebase should 
work smoothly with more recent versions of Gmsh than 2.0. From your post, it's 
unclear whether you've recently pulled the develop branch from github, or 
manually applied the changes in that pull request to an older release. Please 
update both Gmsh and FiPy, then post the specific error messages it returns.


Thanks,

Trevor

Subject: Error: Gmsh hasn't produced any cells!

Hello,

I'm getting an error when trying to run the diffusion circle example. I keep 
getting the following error:

GmshException: Gmsh hasn't produced any cells! Check your Gmsh code.

Gmsh output:


I'm running Gmsh 2.0. Any other version gives me errors with the version number 
despite having fixed the error as described here: 
https://github.com/usnistgov/fipy/pull/442


Does anyone have any suggestions on how I can get Gmsh to produce the cells 
it's supposed to? Or perhaps someone could explain a different method of 
importing a gmsh file? I don't mind creating something in gmsh and then 
importing it separately if that's easier?

Thank you!
