MCE - Marching Cube ELD
Crystallographic software for displaying voxel maps - electron density
MCE is an crystallographic experimental program for 3D and 2D electron density map visualization. The software is mainly focused on visualization of ELD calculated from X-ray diffraction data of small molecules, but it will work for small proteins as well. Download the installation file (default download) or find in "Files" the zip-file with instant copy of the program which does not require the installation. -

MCTDHTools
A library to easily analyse output of the Heidelberg MCTDH code
This project aims to provide a set of routines to easily read in and manipulate the output of the Heidelberg MCTDH code. The goal is to enable a new user to quickly get started with writing custom analysis programs. Also, it should enable more experienced users (== us) to write small, clean, and testable analysis programs, something that seems incompatible with the Fortran-77 code of the Heidelberg MCTDH package. -

RAtom
solves nonlinear Kohn-Sham equation for the neutral atom.
RAtom solves nonlinear Kohn-Sham equation for the neutral atom. The adaptive algorithm based on finite element method (FEM) is implemented. Discretization of the differential eigenvalue problem is done by finite element method with Lobatto polynomials as a basis functions. High order Gauss quadratures are applied in order to obtain the total energy of atom with absolut accuracy of 1E-6 hartree. Disctretization leads to generalized eigenvalue problem, which is solved by procedures from LAPACK libraries. The program is implemented in C++, it runs as a single thread. The implemented algorithm is described in the following papers: 1. Z. Romanowski, "Adaptive solver of a Kohn-Sham equation for an atom", Modelling Simul. Mater. Sci. Eng. vol. 17, 045001 (2009) 2. Z. Romanowski, "Application of h-adaptive, high order finite element method to solve radial Schrödinger equation", Molecular Physics, vol. 107, pp. 1339-1348 (2009). Further questions: romz@wp.pl -

Ultrashort Pulse Propagator
A powerful simulation for designing femtosecond lasers and amplifiers.
This is a simulation package developed for numerical simulation of ultrashort pulse propagation in optical media and pulse generation from mode-locked lasers. Although the code is primarily intended for investigations of fiber links, fiber amplifiers and fiber lasers, it can be applied to any other setting for which the governing equiations are valid. The physics included in the code is based on a generalized nonlinear Schrödinger equation, including higher order dispersion, stimulated Raman effect, gain with bandwidth limitation and saturation, loss, and saturable absorption. Disclaimer: The simulation code is provided free of charge for the use of the academic community only. We kindly ask the users to acknowledge use of the code in academic settings. We do not accept responsibility for any errors or omissions that may be present. Çağrı Şenel, Punya Prasanna Paltani, Fatih Ömer Ilday -

XMDS
Fast integrator of stochastic partial differential equations
XMDS is a code generator that integrates equations. You write them down in human readable form in a XML file, and it goes away and writes and compiles a C++ program that integrates those equations as fast as it can possibly be done in your architecture. -

YCTget
Program to fetch datas from YC-7x7 dataloggers from YCT
We needed a datalogger, we found one. But the supplied VB6 program was very crappy, _really_ unusable, even on old XP machines. So I did mine, able to run under windows and linux. All the fun was to reverse the (binary) RS232 protocol. Our is a YC-727D with 2 thermocouple inputs, but the protocol is the same for 1, 2, 3 or 4 inputs models (YC-717, YC-727, YC-737, YC-747). Bytes orders needs to be checked for 3th and 4nd channels tough. -

stellarics
Inverse Compton emission from heliospheres of sun and stars
Cosmic ray electrons scatter on the photon fields around stars, including the sun, to create gamma rays by the inverse Compton effect. This program computes the spectrum and angular distribution of this emission. The software also includes general-purpose routines for inverse Compton scattering on a given electron spectrum, for example for interstellar or astrophysical source modelling. For further information see these publications: http://arxiv.org/abs/astro-ph/0607563, http://arxiv.org/abs/0801.2178, http://arxiv.org/abs/1104.2093, http://adsabs.harvard.edu/abs/2013NuPhS.239..266O and this conference presentation: https://confluence.slac.stanford.edu/download/attachments/130879399/poster_symposium_sun_2012.pdf and the corresponding conference paper http://arxiv.org/abs/1307.6798 2017 June 16: now available from gitlab https://gitlab.mpcdf.mpg.de/aws/stellarics which will be used for future develpments. -
