You can use open_h5file() method of field class to obtain a filehandle
for arbitrarily named datafile. Then you can supply it as h5file
argument (not dataname) for any output_hdf5 method. dataname has
different meaning - it is a name of dataset in datafile.

Hello, Meep-discuss!
Ok, I should be more specific. My problem involves a cylinder of
epsilon = -8 +0.31i.
I read the manual section that explains how to observe the imaginary
part, but found nothing about negative. So, thank you very much for
clarification on this point.

Dear Steven and Meep users:
Thank you in advance.
I want to calculate the infrared (8-14um)reflection spectrum. The structure is
the following.

Dear Steven and other meep users,
I have a problem with the parallelization of my simulations. We have a cluster
with several nodes. Every node is connected with each other through a one Gbit
Ethernet switch. Every node has two processors with two physical cores, i.e.,
four cores. I have found t

Hi Steven,
Thanks a lot for helping me find out a big mistake I made - that is, I was
confused by the defination of current in MEEP, which is totally different
from that in driving circuit.

I am trying to calculate the phase of my E field inside a waveguide and i was

I want to manipulate the output filename in c++ interface. I have browsed

From your output, it sounds like the problem is harminv, not Meep per
se. Can you verify that running without harminv works okay, and e.g.
outputting the data at some point as a function of time looks okay
(e.g. not blowing up etc.)?

This is just the Scheme programming language. There are lots of

I need help to use a negative value to epsilon . I have not found an
explanation in the manuals for it.
