Iterate is an implementation of the Bravais-lattice-finding algorithm from: Andrews and Bernstein, Acta Cryst. (1988). A44, 1009-1018 Lattices and Reduced Cells as Points in 6-Space and Selection of Bravais Lattice Type by Projections.

...Its main purpose is the simulation of compressible flows in accretion disks. The underlying numerical solution method belongs to the family of unsplit conservative finite volume TVD schemes. The method is 2nd order accurate in space and uses high order Runge-Kutta and multistep schemes for time evolution. In addition to the pure advection code several source terms have been implemented including viscous diffusion and gravitational acceleration. Fosite is written with object-oriented patterns in Fortran 2003 and follows the Structure of Arrays (SoA) layout, operating on generic field datatypes. ...

...The code includes built-in fitting procedures with a wide variety of constraints; stochastic SR energy loss; the tracking of synchrotron radiation (SR) Poynting vector; space charge models; various Monte Carlo procedures, etc. Contact: francoisgmeot@gmail.com Documentation (History of accelerators that zgoubi deals with, theory, tutorials): https://link.springer.com/book/10.1007/978-3-031-59979-8 https://link.springer.com/book/10.1007/978-3-031-16715-7, Chap. 14.

We are proud to introduce version 5 of CAMPARI. We have added a number of new features, most notably a Python interface for interpreting user-supplied code (with the help of ForPy), a novel trajectory storage standard (with the help of libpqxx/PostgreSQL), and a module for performing transition path theory. Naturally, CAMPARI continues to provide the reference implementation of the ABSINTH force field paradigm and implicit solvation model. CAMPARI is a joint package for performing and...

NESSIE is a modern first-principle calculation software that can adequately address the need for ever-higher levels of numerical accuracy and high-performance in large-scale electronic structure simulations, as well as pioneer the fundamental study of quantum many-body effects in a large number of emerging nanomaterials. NESSIE is an electronic structure code that uses a real-space FEM discretization and domain-decomposition (DD) to perform all-electron ground-state DFT and real-time excited-state TDDFT calculations. The code is written to take advantage of multilevel parallelisms of the FEAST eigenvalue solver to target systems containing many distributed-memory compute nodes. The real space mesh is generated using the software tetgen.

...News: V2.1 with many improvements released on 07/15/2016. Sources and binaries are available. RMG is a density functional theory (DFT) based electronic structure code that uses real space grids to represent wavefunctions, charge densities and ionic potentials. Designed for scaleability it has been run successfully on systems with thousands of nodes and hundreds of thousands of CPU cores. It is currently under active development and contributions are gladly accepted.

...It can generate scattering cross sections over specified angular ranges and total absorption cross sections. It was initially developed to aid work with optical particle counters (OPC) especially when CONverting data between cross section and diameter space. These methods are described in Rosenberg et al. 2012, Particle sizing calibration with refractive index correction for light scattering optical particle counters and impacts upon PCASP and CDP data collected during the Fennec campaign and CDP data collected during the Fennec campaign, http://www.atmos-meas-tech.net/5/1147/2012/amt-5-1147-2012.html

The Open Source Space Flight Dynamics (OSSFD) project is intended to provide the community with an open source solution to space flight dynamics.
