LAMMPS is a classical molecular dynamics simulator designed for parallel machines. It can model atomic, polymeric, biological, metallic, or mesoscale systems using a variety of force fields and boundary conditions and is easy to modify or extend.

function library efficiently solving the Nearest Neighbor Problem (also know as the post office problem).

ProtoFit is software for modeling the acid/base behavior of surfaces. The software is used for parameterizing surface protonation models and for visualization of potentiometric titration data.

Scalable Molecular Analysis Solver for High-performance computing systems (SMASH) is massively parallel software for quantum chemistry calculations and released under the Apache 2.0 open source license. It is currently capable of energy, analytical gradient, and geometry optimization calculations of Hartree-Fock theory and Density Functional Theory (DFT), and energy calculations of Second-order Moller-Plesset (MP2) perturbation theory. DFT calculations can be performed on 100,000 CPU cores with high parallel efficiency.

Computational Fluid Dynamics (CFD) solver aimed to solve multi-physics problems on unstructured grids (inviscid Euler, Navier-Stokes flows, Heat transfer). F90 based. MPI, cgns, Metis libraries used.

g2 is an easy to use, portable and powerful 2D graphics library. It provides a comprehensive set of functions for simultaneous generation of graphical output on different types of devices.

http://loto.sourceforge.net/ hosts 4 projects of free software related to materials science and physics. They are loto, feram, compasses and xtalgrowth.

The CFD General Notation System (CGNS) provides a standard for recording and recovering computer data associated with the numerical solution of fluid dynamics equations. WE HAVE MOVED! Very old (unsupported) stable releases can still be found here, but the new repository is at https://github.com/CGNS

The DUNS (Diagonalized Upwind Navier-Stokes)code is a 2D/3D, structured, multi-block, multi-species,reacting, steady/unsteady, Navier Stokes fluid dynamics code with q-omega turbulence model. It currently uses a diagonalized ADI procedure with upwind diff

Fortran binding for GMP library. Currently gfortran compiler supported on Linux and MS Windows (MinGW) platforms. Included Fortran program for solving Archimedes's cattle problem.

The purpose of this project was to prepare gfortran for integration into gcc. Since this integration was completed in the summer of 2003, this project is now finished. You can find information about gfortran on http://gcc.gnu.org/wiki/GFortran/

Mendel’s Accountant is a biologically realistic, forward-time, parallel, numerical simulation program which models genetic change within a population, as affected by mutation and selection.

PUPIL (Program for User Package Interface and Linking), is a software environment that allows developers to link quickly and efficiently together multiple pieces of software in a fully automated multi-scale simulation. More specifically, it supports QM/MM MD simulations where the user might choose among any of the different MD engines and QM engines, which are connected to PUPIL as external programs through a tiny specific interface. One of the main advantages here is that the user can use most of the functionalities that may have those external programs interfaced without the necessity to be reimplemented again on independent interfaces. In fact, this simulation interface concentrates all the common code involved in the coupling terms of the QM/MM approach.

Pyfort is a tool for creating extensions to the Python language with Fortran routines. It supports F77-interfaced routines now, with plans for supporting more of F90 later.

SIGPROC - a collection of signal processing programs developed for pulsar data reduction has been developed and maintained since 1999. The package is used to search for and visualize the presence of pulsed signals in noisy radio astronomy data.

Algae is a programming language for numerical analysis. We wrote it because we needed a fast and versatile tool, capable of handling large systems. Algae has been applied to interesting problems in aerospace and related fields for more than a decade.

Molecular Graphics and Dynamics. Molecular model builder. Part of the Ascalaph Designer http://sourceforge.net/projects/asc-designer/ project. Windows & Linux.

MaxFem is an open software package for electromagnetic simulation by using finite element methods. The package can solve problems in electrostatics, direct current, magnetostatics and eddy-currents. Since version 0.4.0, MaxFEM requires Python 3. We have moved the installers to the MaxFEM website (see below). In order to improve MaxFEM, we will require you to fill out a simple form before downloading them.

A spectral element method for 2D wave propagation and fracture dynamics, with emphasis on computational seismology and earthquake source dynamics.

Project to calculate and distribute the general relativistic corrections to clock rates for the surfaces of various solar system bodies. These corrections are also known as time ephemerides.

This library is a Fortran 95 gnuplot interface for some Unix like OS'es. This provides some routines that enables direct access of a child gnuplot session from a Fortran 95 program. You will need a copy of fortranposix to make this work.

Framework for blockstructured adaptive finite volume methods. Provides MPI-parallelized variant of the Berger-Oliger AMR algorithm for Beowulf-clusters. Uses Clawpack. Visualization and conversion tools for HDF4 files included.

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
