file for a more detailed listing).

Meep 0.10.1
13 November 2007
- Bug fix in
flux_in_box
, which accidentally returned the flux
multiplied by the number of processors, instead of the flux.
- Bug fix in epsilon averaging for structures including metals
(ε < 0), fixing an instability.
- Bug fix in
output-png
when running in parallel (removing race condition). - Fixed bug that disabled subpixel averaging for dimensions=1 (thanks
to Mischa Megens for the bug report).
- Fixed bug that caused
output-tot-pwr
to stop Meep with an error message;
thanks to Vyacheslav Sokolov for the bug report.
- Make
at-every
step functions less susceptible to rounding errors;
thanks to L. Le Guyader for the bug report.
- Fixed bug in dispersive media that wasted memory on parallel machines
(the polarization memory was not parallelized); thanks to J. L. Silva for the bug report.
- Bug fix in
output-png+h5
, thanks to a report by Chad Husko. - Fixed several deadlocks that could occur when the parallel Meep
is used with a serial HDF5 library (we continue to recommend using the parallel HDF5 library with parallel Meep, however). Thanks in part to Lingling Tang for his bug report.
- For maintainer-mode, improved detection of Haskell package names;
thanks to Liang Huo for the bug report.
Meep 0.10
21 August 2006
-
eps-averaging?
is now turned on by default (in libctl interface), using much-improved algorithm by Ardavan Farjadpour. This greatly improves accuracy, and also allows continuous tuning of geometric parameters. (See our upcoming paper in Optics Lett., with a preprint at Citing Meep.) New input variablessubpixel-tol
andsubpixel-maxeval
to control the accuracy of the subpixel averaging. - Support for χ(2) (Pockels) as well as χ(3) (Kerr) nonlinearities.
- Symmetries no longer require the cell size to be an even number of pixels. Previously, Meep exited with an error in this case, whereas now it simply adds an extra pixel to the cell size as needed.
- New
with-prefix
step function to allow you to use a differentfilename-prefix
for selected outputs. - New feature for
output-png
: built-in shell variable$EPS
that refers to the last-output epsilon.h5
file, which you can use to easily add dielectric contours/overlays to the field output image. - Added
output-png+h5
function that outputs both.png
and.h5
files. - New functions
flux-in-box
,electric-energy-in-box
,magnetic-energy-in-box
, andfield-energy-in-box
(convenience wrappers around C++ functions). - Bug fix in Kerr nonlinearity:
chi3
was accidentally scaled by factor. - Bug fix: if you specified three or more symmetries, at most two symmetries were used (ignoring the rest).
- Bug fix in
rotate2
symmetry, which wasn't working correctly. - Bug fix in
add-flux
for multiple flux regions, thanks to K. Choi. - Bug fix in
harminv
where it wouldn't allow you to callharminv
more than once for the same run loop; thanks to Aristos Karalis. - Bug fix in
save-flux
/load-flux
that prevented it from working properly without output directories, thanks to Karl Koch. - Fixed abort that sometimes occurred due to rounding when the source was the same width as the cell (thanks to G. J. Parker).
- Fixed minor build problems on Cygwin, SGI, and other systems, thanks to Christopher Kang, Robyn Landers, Florencio Garcia, and others.
Meep 0.9
1 April 2006
