2.0.0 - 2006/02/17
-
Curvilinear coordinates: This is one of the main novelties. A general framework is implemented, and several different curvilinear systems are implemented. At this moment only the coordinate transformation of François Gygi is working well. The efficiency gained from using curvilinear coordinates can be as large as a factor of 2 or 3 in computational time. However, note that this method is not well suited if you want to move the ions.
-
Parallelization in domains: You will be able to run octopus in parallel in domains. This means that not only the real time is reduced, but also the memory is shared among the different nodes. Also some parts of the code will have a mixed parallelization. For example, the time-dependent propagation will be parallel both in domains and in states. This was basically the work of [[Florian|Florian Lorenzen]] and [[Heiko|Heiko Appel]].
-
Static response properties: Now Octopus can calculate the static polarizability and the first static hyperpolarizability. These are obtained by solving a Sternheimer equation. We have also planned the computation of vibrational properties. This was done mainly by [[Xavier|Xavier Andrade]] and [[Hyllios]]. Instructions here
-
A larger selection of exchange-correlation functionals. This came with the development of the NANOQUANTA xc library. We have by now all LDAs and some GGAs. This library is also used by the newest version of [http://www.abinit.org/ ABINIT]. We expect that the number of xc functionals available will increase rapidly.
-
A multigrid solver for the Poisson equation. Implemented by [[user:Xavier|Xavier Andrade]]. (Note: not working with curvlinear coordinates)
-
Periodic Systems. Finally, the ground state seems to work at least for cubic systems. There is still some work remaining in order to run a time-dependent simulation. Implemented by [[user:Carlo|Carlo Rozzi]] and [[Heiko|Heiko Appel]].
-
Spinors and Spin Orbit. Yes, spin-orbit works but only with HGH pseudopotentials. The calculations are quite heavy, though ;). Brought to you by [[Alberto|Alberto Castro]] and [[user:Micael|Micael Oliveira]].
-
Multi Subsystem Mode. Like [http://www.abinit.org/ ABINIT], now you can perform multiple runs with only one input file. Implemented by [[Heiko|Heiko Appel]].
