Looks like the actual node that is running meep in your cluster isn't
seeing your PATH variable. Ask your sysadmin on which file you must set
your path to so that the definition is propagaged.
For now you could try to "man" your bsub command to see if it accepts
env variable arguments. Try,

hi shiv,
Here is my best guess - someone correct me if I'm wrong. Try one or
both of the following:
1. increase the width of the gaussian source. It seems to be a very
tight spike: check if it is comparable to resolutions. The grid will
propagate a pulse better if is spread out across more

hi Shiv,
These are the functions I use to convert from real units to the meep
system. cc-ing the Meep mailing list should anyone else want to comment
or correct these:
(define C_0 299792458.0); m/s
(define (meepify-length real-length lscale) (/ real-length lscale))
(define (meepify-velocit
One of the reasons for seeing a pulse multiple times could be
reflections. In your case, your PML is 2 cells wide (thickness is 0.1 at
resolution of 20). How about making your PML thickness 1.0 instead?
Your pulse could be bouncing back and forth between the two Y walls
inside your dielectric.
Hi Francisco,
"car" and "cdr" are list-access/manipulation functions in
Lisp/Scheme, if I remember my functional programming correctly. Try
looking up references related to these to understand the error messages.

Hi all,
Meep's polarizabilities are specified using omega, gamma,
delta-epsilon, sigma etc. Should the gamma be specified in units of c/a
or 2PI*c/a?
This doubt stems from the Johnson and Christy paper on optical

Hi Dr. Johnson and other MEEP/FDTD knowledgeables,
I was thinking about why MEEP should allow only a real dielectric
constant. In the monochromatic case it would make sense to evaluate the
dielectric function at the frequency-of-interest \omega_0 and plug that
into Maxwell's equations, simpl
Looks like a guile/guile-devel version mismatch to me. Your install

Hi all,
Could someone clarify the meaning of this term? I'm aware of what it

Any useful links/resources?

You might have to tell mpirun (or whatever load-manager your cluster

Objects such as blocks, cylinders, cones etc. are geometric objects.
Look up the MEEP libctl reference for a list of allowed types.
A collection and arrangement of these in your simulation volume is the

I'm in the process of decrypting MEEP's C++ part. what I dig up I add to
the C++ reference wiki page.
MEEP's interface with libctl is in the libctl/ subdir, not in the src/
subdir. Also, some of the header files are generated from basic
specifications in the hsrc/ subdir using Haskell (ghc).

In your meep "unpack" dir, run
./configure --help
Look at the documentation for CFLAGS, CPPFLAGS, CXXFLAGS, LDFLAGS. You
might just need to set CPPFLAGS and LDFLAGS but if that doesn't work try
setting the others too to point to the structure inside your home dir.
On the gcc command lin

If you have super-user access to your machine then installing
guile-devel, libctl and libctl-devel will correct dependency issues.
Using the MEEP libctl front-end is great for prototyping your program.
If you want to bypass these because of issues with configure then try to
look for libctl head
Try the one or all of the following:
1. set the LD_LIBRARY_PATH environment variable to include /usr/local/lib
2. include on your configure command line:
CPPFLAGS=-I/usr/local/include CXXFLAGS=-I/usr/local/include
CFLAGS=-I/usr/local/include
Also, open config.log in your favourite editor an
./configure --without-libctl
This should work. This will only spit out libmeep.a and no meep
executable in the libctl/ subdir.
cheers!

Hi Dr. Johnson,
I understand polarization to be the material property. So
polarization would then be the state of the material with the given
polarizability and under the influence of the sources at a particular
time-step in the simulation?
I also see a volume variable 'v' for polarizabi
itives. A scenegraph
for this would be overkill. Simply adding an extra orientation parameter
may be enough. But if we do this would it be able to handle obliquely
oriented line and plane sources?
Thanks

Hi all,
Regarding the flux-in-box function, it needs a direction, and a
box-shaped volume. I don't clearly understand this. The example in the
documentation presents a y-z cross-section of unit size and defines
'dir' to be X. I understand this to be a box whose x-length spans the

Hi all,
I was trying to understand the MEEP C++ interface by reading the
sources and I had a question:
What is the "chunk" concept? How does the "fields" class differ from
the "fields_chunk" class, the "structure" class from the
"structure_chunk" class? What is "dft_chunk"?
Thanks,
Manoj
