ADDA 0.79 released
Maxim Yurkin
I am glad to announce that new version of ADDA (0.79) has been released. The most important changes are:
* Added using SLURM job ID, when available.
* Saving of granule coordinates to a file was implemented.
* The code was tested for 64bit, implementing a number of corrections/improvements.
* New shape 'axisymmetric' was added. The internals of shape generation routines were adjusted so that shape can now
define the absolute size of the particle.
* A new option '-scat fin' was implemented, which uses finite dipole correction for calculation of Cabs and Cext.
* Breakdown detection of iterative solvers was improved.
* '-prognose' command line option was replaced by '-prognosis' (correct spelling). The former is still operational but
marked as deprecated.
* The code was transformed to C99 standard without using its parts, which are not yet widely supported by compilers
(such as inline and complex). Explicit support of this standard is required during compilation. Some style changes were
done, and some work in this direction is still due.
* Affiliation of one of the author (Maxim Yurkin) has changed to Institute of Chemical Kinetics & Combustion
(Novosibirsk, Russia). Full name of the package was changed from 'Amsterdam DDA' to 'ADDA'. This does not change the
global strategy of ADDA development.
* Code repository has been moved to Google Code (http://a-dda.googlecode.com/). Google groups adda-announce
(http://groups.google.com/group/adda-announce), adda-discuss (http://groups.google.com/group/adda-discuss) and
adda-develop (http://groups.google.com/group/adda-develop) were created to facilitate interaction with users. These
replaces the previous mailing list
* Copyright was updated to GPL 3 (http://www.gnu.org/copyleft/gpl.html).
* To-do list was replaced by issue tracker (http://code.google.com/p/a-dda/issues).
* Additions to the manual: short history of earlier ADDA development, description how to add new beam type and new
command line options, a small summary of the comparison of the DDA with the FDTD, discussion of difference between two
ways to calculate Csca, possibilities to improve the accuracy of these calculations, and connection between differential
cross section and the Mueller matrix.
* Information on how to cite the manual was added to its first page. It includes a direct link to the particular version
of the manual on Google code.
* Manual license is now explicitly set to Creative Commons Attribution 3.0 license
(http://creativecommons.org/licenses/by/3.0/).
* Several minor bugs were fixed.
You are advised to upgrade to a new version, which can be downloaded (both main package and, if needed, executable for
32-bit Windows) from: http://code.google.com/p/a-dda/downloads/
Old ADDA homepage at University of Amsterdam (http://www.science.uva.nl/research/scs/Software/adda/) will be updated
withing a few days to show information about the new release.
I would like also to use this possibility to bring your attention to the adda-discuss Google group. It seems to become a
nice forum for discussions concerning DDA simulations. For instance, there has been a thorough discussions on accuracy
of simulation of absorption cross section of gold nanoparticles in near-infrared. So,
1) If you have any questions about ADDA, direct them to adda-d...@googlegroups.com .
2) Consider joining this group and participating in existing discussions or those newly created by other users.
See http://groups.google.com/group/adda-discuss for details.
One more thing: if you look at main ADDA page at Google code (http://a-dda.googlecode.com/) there is a small badge with
text like "# Users. I use it!". If you actively use ADDA please consider clicking on this badge to indicate this fact.
This will require you to register at ohloh.net (which is a platform with useful tools for open-source projects), but it
will support the authors by knowing more about ADDA users.
Best regards,
Maxim Yurkin.
