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
