Hello,
You do not need DL model to describe organic materials, they are described
using regular dielectric permittivity (complex if you want to account for
dielectric losses). You can determine them from the known refractive
indices. For ITO it might be different, because it is conductive and in

Hope it helps,

Hi,
As far as I remember, geometric primitives are defined in Scheme
wrapper, not in the underlying meep library. Therefore they can not be
wrapped by python layer. So the answer to your question is No, there
is no geometric primitives in python-meep. In simplest case you can
define the sphere in

Hello!
As far as I know there is no standard file that meep could import as a
3D model. If you do not mind python then I would suggest you to use
1) Free-cad http://sourceforge.net/projects/free-cad/files/FreeCAD%20Linux/
2) python-meep
You still have to write a layer that would transform cad
Once upon a time I had prepared packages of meep for ubuntu at Launchpad.
Most probably, they can be with a very small effort installed on a Debian.
If not, you can just fetch deb src from that repository, and rebuild it for
you system with e.g. pbuilder or prevu.
With best regards,
Shawkat

Hi everyone,
I have a problem in meep installation.I have installed the file
libhdf5-serial-1.6.6-0_1.6.6-4_i386.deb.
You should also install corresponding -dev package.

A quick glance at your examples reveals several differences in your examples.
1) In C++ case, the source is very close to the PML area (remember
that origin is in the corner, that's why source at 1.1 is very close
to the PML, which ends at 1.0). In Scheme example source is alsmost in
the center
Hi!
If I correctly understand you, you want to extend the simulation and
perform custom specific fields calculations, made on specified
regions, along the FDTD calculations.
In this case you have several choices, all of them are undocumented,
but may be figured out looking through sources. If
In your case, have you witnessed this kind of unbalanced behavior (unbalanced

1) You didn't provide any details on the layout of your cluster. It is
hard to guess if you have a several dual-cores with 16Gb memory, or
they are 6 cores and you are running only on one of them.

My guess is that mpirun tries to setup the connection to all nodes
(every cpu core is counted as a single node) and fails. OpenMPI may
use different methods for connection to nodes - ssh, rsh, shared
memory etc. In your case it looks like trying rsh - this is AFAIK
default OpenMPI behaviour. Read
It is well known - small simulations are better with single core than
multicore. In order to get a reasonable speed-up on a multicore a
simulation should exceed e.g. 100 Mb (in occupied memory). Just use a
higher resolution and see how the speedup will change. If increase of
resolution leads to
Hi!
Stepped frequency continuous wave, as you describe it, seems
inpractical for me. Any coarse frequency change will cause high
harmonics wave, which may lead to numerous artifacts. Even using very
small frequency steps you should still make sure that any such change
will not cause abrupt change

I looked at the Python bindings when you first posted about them, thank-you
for your effort. I have returned to them today since I have been trying to
figure out whether there is a command such as stop-when-fields-decayed for
the C++ interface.
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.
2009/9/19, 李志强 lzq0011...@gmail.com:
Probably, you would better look at generic src_time class. AFAIK, you
just have to override its dipole(time) function to whatever function
you need. I don't have a working c++ example and would be glad if
anyone provides it.

- there is a special argument - num_chunks in class structure.
Is it supposed to be the number of available processor cores, so that
calculation domain optimally split among nodes ?
And the last - Are there any hints for using meep with mpi support ?
