That's because you have to run its normalization case first, as explained
in the tutorial.
The file attached gave me the error I reported earlier (meep: Cannot

I added a statement to print out your cell size:
(print "cell size = " size-cell-pml " x " (* 3 size-cell-pml)
", resolution = " resolution "\n")
The output is:
cell size = 0.66 x 1.98, resolution = 1.0e8
So, you are specifying a computational cell of 0.66e8 x 1.98e8 pixels;
it's not surprising that there is an error!
Think about what you are doing: you want a computational cell size that is
about a meter squared, but you want a resolution of less than a micron.
There is no way you are going to be able to simulate this on any computer
with a finite-difference method. Meep won't perform miracles for you.
