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

Diofantos is a library for the solution of equations that arise in physics. It deals with ordinary differential equations (ODE), partial differential equations (PDE), including grid generation, and integral equations.

We have moved, the project is now at http://distancesampling.org

The ELPA library provides highly efficient and highly scalable direct eigensolvers for symmetric (hermitian) matrices. Branch clone of the ELPA library, 2022.05.001 version. No changes are introduced, no intention to modify the code. Cloned in case the repository at elpa.mpcdf.mpg.de becomes inaccessible.

This software is a computer program whose purpose is to fortran mathematics library and some solve linear equation in high performance computing. I create this software for for my last year of engineer school (Scientific Computing Option)

NOTE: Development continued at GitHub! Current version is higher than 1.2.0. GADfit is a Fortran implementation of global nonlinear curve fitting, based on a modified Levenberg-Marquardt algorithm. Global fitting refers to fitting many datasets simultaneously with some parameters shared among the datasets. The fitting procedure is very fast and accurate thanks to the use of automatic differentiation. The model curves (fitting functions) can be of essentially arbitrary complexity. This includes any nonlinear combination of elementary and special functions, single and/or double integrals, and any control flow statement allowed by the programming language. See the latest user guide under Files.

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/

(We have migrated this project to github [June 1 2015)] http://github.com/msg-byu/enumlib). The source files have been removed from sourceforge. Go to github (link above) for the latest copy. <<<< OLD SUMMARY >>>> A Fortran 95 implementation of an algorithm for generating derivative structures of a parent lattice.
