That's great to hear. What sort of applications are you working on?
I'm interested in modeling reaction-diffusion in biological systems. We
have nice data from imaging techniques that provide quantitative estimates
of protein and mRNA concentrations in a developing fruitfly embryo.
See:

The embryo is not quite a sphere but it ends up that at this stage of
development,
all the nuclei are on the surface so a thin shell is probably a reasonable
model. Your extrusion code is perfect.

You have the right viewer, but the wrong mesh. We're actually rather
surprised that GmshImporter2D() was willing to import a mesh with
three spatial dimensions. I've posted an explanation of how we went
about it at https://www.matforge.org/fipy/wiki/SurfaceOfSphere
Thanks! This is quite useful. After a little work, I managed to get your
code running. Are there command line options to get gmsh 2 to spit out
1.0 file format? I ended up using "save as.." from the ui.
As per the warning, the vertex/face ordering on the faces seems
incorrect, e.g.

I assume the ordering is correct as far as the solver goes :-)
Thanks for the quick response; I will keep you updated.
