Hi Steven,

I found the following error while calculating the transmission spectrum around 
a waveguide bend in the tutorial. This shows up only if I allow the following 
line to be executed:
(if (not no-bend?) (load-minus-flux "refl-flux" refl))

Copy of the output:

in the tutorial section:
Initializing structure...
Working in 2D dimensions.
    block, center = (-2,-11.5,0)
         size (12,1,1e+20)
         axes (1,0,0), (0,1,0), (0,0,1)
         dielectric constant epsilon = 12
    block, center = (3.5,2,0)
         size (1,28,1e+20)
         axes (1,0,0), (0,1,0), (0,0,1)
         dielectric constant epsilon = 12
time for set_epsilon = 0.458859 s

meep: error on line 243 of h5file.cpp: error opening HDF5 input file

All tests during Meep install were fine but this seems external to the 
simulation (i.e. HDF5). Any hint as what might be wrong here?

Thanks!

Fred.
