[mpas-developers] 1/10 degree problems

[Michael Duda]

Thanks, Xylar -- I missed that part completely!

I was also wondering whether there could be some problem with the
code in handling larger grids; to my knowledge, the code hasn't
been tested with grids having more than 2621442 cells. I'll try
generating a larger mesh and see whether I can get a successful
run through here at NCAR.

Cheers,
Michael
