PyGTS is a python package used to construct, manipulate, and perform computations on triangulated surfaces. It is a hand-crafted and pythonic binding for the GNU Triangulated Surface (GTS) Library. THIS PROJECT IS NOT BEING MAINTAINED.
FElt is an open source system for finite element analysis, primarily for mechanical problems. FElt includes command line tools, an X11 interface for pre- and post-processing, and a Windows editor interface with some post-processing capabilities.
Generate interest, access liquidity without selling, and execute trades seamlessly. All in one platform.
Geographic restrictions, eligibility, and terms apply.
GMM-GMR is a light package of functions in C/C++ to compute Gaussian Mixture Model (GMM) and Gaussian Mixture Regression (GMR). It allows to encode any dataset in a GMM, and GMR can then be used to retrieve partial data by specifying the desired inputs.
Qspline does quaternion interpolation such that the quaternion and angular rate and acceleration vectors are continuous functions of time, while maintaining quaternion normalization.
These simple programs are for doing data reduction and then display of columns of tab delimited data. They are designed to be piped together so you can do multiple things at once. This means they typically read from stdin and output to stdout.
An object-oriented partial differential equation (PDE) solver, written in Python, based on a standard finite volume approach and includes interface tracking algorithms. *WARNING* The project is no longer using Sourceforge to maintain its repository.
SciGraphica is a scientific data visualization and analysis application, supplying many of the basic plotting features for 2D and 3D charts. It features opening several worksheets and plots to work with at the same time and PS output.

An automatic 2D Delaunay mesh generator and solver for Finite Element Analysis. Can solve 2D field problems (Poisson and Helmholtz Equations). Can use LAPACK/ARPACK solvers producing OpenGL/Postscript output. Uses C/GTK/GTKGLExt/MFC. Runs on Win32/Unix.
The fst2v5d package converts data stored in the Canadian RPN Standard File (FST) format into Vis5D format. FST files, commonly used to store meteorological data, are scanned by fst2v5d to generate both 4D fields and independent topography input files.
CCOUNT is a free package for market research data cleaning, manipulation, cross tabulation and dataanalysis. Similar to, and uses the same syntax as, SPSS-MR Quantum, a well known commercial package for processing market research data.
Geomatrix, collection of C/C++ libraries to be used for symbolic description of n-dimensional geometric models. Operates internally with a representation that constructs complex objects based on primitives, allowing loss-less modifcation of models.
