A framework for solving partial differential equations
Overture is a framework for solving partial differential equations (PDEs) in complex, possibly moving geometry. Overture uses overlapping grids to represent the geometry. The software includes grid generation capabilities, PDE solvers for fluids, solids, and fluid-structure interactions (FSI) as well as electromagnetics.
The MetCal/SPA package provides diagnostic resources for users and developers of meteorological apps. The Shared Procedure Archive is a dynamic set of file I/O, analysis routines and APIs for third party packages accessible through the MetCal GUI.
The PDL module gives standard perl the ability to COMPACTLY store and SPEEDILY manipulate the large N-dimensional data sets that are the bread and butter of scientific computing.
Freemat is an interpreted, matrix-oriented development environment for engineering and scientific applications, similar to the commercial package MATLAB. Freemat provides visualization, image manipulation, and plotting as well as parallel programming.

Runge is an Interactive Solver for Systems of Differential Equations
... derivatives (Jacobian matrix, for example) it does that analytically, i.e. without using numerical methods.
It's portable. It works on Windows and Linux 32 and 64 bit and Mac OS X 64 bit.
It's open. It allows you to implement and embed your own algorithms (aka "solvers").
It's easy to use. It allows to export results to MS Excel and MATLAB.
It's multilingual. It currently supports Englis and Russian languages.
It's free. It's distributed under the Boost Software License.
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.
