ORTEP-III with CAIRO graphics backend
ooc-cholesky is an open source Out-Of-Core (meaning: intended for memory-limited environments or large datasets) Cholesky solver.
ThanDxflib is a library, written in Fortran 77, which makes the creation of .dxf drawings easy. The dxf files may be read by any CAD program.
LIB_VTK_IO is a Fortran library to write and read write and read data conforming the VTK standard, Visualization Toolkit from Kiteware, both binary and ascii.
SPHear is a coupled smoothed particle hydrodynamics (SPH), finite element (FE) fluid-solid interaction analysis code for dynamic problems.
A library to compute the electron and chemical kinetics on plasmas
PLASMAKIN is a package to handle physical and chemical data used in plasma physics modeling and to compute gas-phase and gas-surface kinetics data: particle production and loss rates, photon emission spectra and energy exchange rates.
Portable replacement for OpenVMS system libraries
Have you ever inherited a legacy application that runs on OpenVMS but wanted to move it to a more modern - and better supported - Operating System? If so, libmodevo is intended to help. The idea behind libmodevo is to develop as complete as possible set of portable functions that replicate the functionality of the system libraries under OpenVMS. By "OpenVMS system libraries" we mean the SYS$, LIB$, STR$, OTS$, SMG$ libraries and other similarly named functions.
A unified flow solver in a unstructured staggered mesh framework combine with a sharp interface immersed boundary approach. Presently 2d, but final versions are expected to be parallel and 3d for handling complex applications.
GridPACK is a community-developed open-source collection of code for use in power systems research, analysis, and operation.
A package of programs for performing extended Hueckel calculations on molecules and solids and visualizing the results. Visualization functionality for some quantum packages (ADF and LMTO) is also provided.
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.
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.
Sculptor is a phase-vocoder-based package with real-time capabilites. You can use it to fiddle with soundfiles in the frequency domain, changing pitch and duration independently.
MatLisp is a package for Common Lisp for handling matrices with real-valued or complex-valued elements. BLAS is used for elementary matrix operations and LAPACK is used for linear algebra routines.
error function and related functions in pure standard Fortran 2008
Fortran 2008 added 3 new intrinsic functions: erf, erfc, erfc_scaled. However, they take only real arguments. This package provides a BSD licensed Fortran 2008 module with erf(z), where z is a complex argument. The calculation is based on calculating w(z), the Faddeyeva (plasma dispersion) function. Two algorithms are implemented: TOMS 680 and 916, http://www.netlib.org/toms/. The simple test program calculates values in the Abramowitz, Stegun.
Stress intensity factor (SIF) calculation from crack tip displacements
The code implements Muskhelishvili's complex function approach to calculate 2D stress intensity factors (modes I+II) from crack tip displacement fields. Surface displacements can be used with a plane stress elastic model. The code uses power/Fourier series expansion and a conformal mapping of an ellipse onto a circle.
A place for IBM mainframe programs (and programmers)
This library provides OCaml-interfaces to the BLAS- and LAPACK libraries.
The U.S. Office of Surface Mining is building a Linux Cluster Supercomputer from used PCs for introduction of Linux into the civilian federal government space.
MagCAD is a set of tools for reconstructing 3D meshes from medical images such as MRI scans and ultra-sound. Resulting meshes are designed for CFD and visualisation
AUTO is a publicly available software for continuation and bifurcation problems in ordinary differential equations originally written in 1980 and widely used in the dynamical systems community.
An easy to use, yet save and fast linear algebra library. LinAl is designed to be compatible with the one and only true language for numerical computations, which is FORTRAN. It is based on STL containers and algorithms.
Questa e' una libreria con alcune utilita' per la gestione di file contenenti grib, ossia dati meteo codificati secondo lo standard del WMO. Questa libreria necessita del software di decodifica sviluppato da ECMWF, o la libreria PICOGRIB rilasciata GPL.
