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.

Voxel CAD. Open source voxel editing and analyzing software. Edit and create multi-material voxel objects. Simulate the dynamics in a quantitative physics sandbox to test engineering designs or make moving creatures. www.voxcad.com for videos.

A python gear generator that serves as CAE/CAD-preprocessor for involute gears based on pythonOCC. It allows for the computation of dynamic properties and the creation of exact geometries from a minimal input set. PyGear can simulate the tool geometry and kinematics of standard gear hobbing tools to generate precise flank, tooth root and tip geometries. Disclosure: the software is open-source and free to use thanks to support received from http://smithbot.com, the easy-to-use AI crypto bot trading platform. SmithBot didn't exert any influence on the project.

Linux TinyCad, or LiniCad, is a tiny CAD used for educational purposes. It is written in Python/Tk and its goals are to be as programmatically easy and small as possible.

Fachwerk calculates strut-and-tie models used by structural engineers for analysing and designing reinforced concrete structures. The program only uses the equilibrium conditions, thus it is not assuming elastic behaviour.

The ADG library (Automatic Drawing Generation) is a set of functions focused on automating the drawing of mechanical parts. It is not a CAD system but a GObject-based library where a custom application can put common CAD entities such as paths, hatches and dimensions, to automatically create technical drawings. A demo application is provided in order to show the capabilities of the canvas. Although it is possible to interact with the library directly in C (that is what the adg-demo program is doing), the canvas is expected to be used from higher level languages, much in the same way as what done in the GNOME stack. Lua bindings based on LGI are already provided out of the box. The adg-lua project, downloadable from the "Files" section, provides Lua programs and demos that leverages these bindings.

Fachwerk3D calculates three-dimensional strut-and-tie models used by structural engineers for analysing and designing reinforced concrete structures. The program only uses the equilibrium conditions, thus it is not assuming elastic behaviour.

QroCAD is a beginner-friendly CAD software available for both web and desktop.

This application is intended to be a tool for easy, almost automatic, creation and calculation of gear transmission finite element models. It consists of a geometry and mesh generator based on GMSH and a finite element model based on GETFEM++.

ThanCad is a 2dimensional cad, with limited 3d support and raster inclusion capability and emphasis in engineering. It is being written in Python and since it uses the Tkinter library, it is platform independent.

Line-drawing and polygon-filling rasterization algorithms in Java. Simple 2D package and more complex 3D package with Z-buffering. Texture mapping not supported at the moment. Color interpolation for lines, Gouraud shading for polygons fully supported. Floating point vertex coordinates, not integer. Pixel-level aliasing, not endpoint aliasing. Doesn't use Bresenham line style! Works with all Java versions. No external dependencies. Suitable for study in academic institutions, especially as related to line-drawing accuracy. Particular attention to detail concerning chopping of accumulation errors, using a cast from 64 bit to 32 bit strategy, in the interval [1.0,2.0). Individual pixel errors with overlapping polygons or line segments are about one in a billion, but I can't reproduce any errors at the moment by using random number generation with tens of millions of cases. Emphasis not only on correctness, but also on performance for real-world use or hardware implementation.

ST je stavařská nadstavba pro AutoCAD a IntelliCAD napsaná v AutoLISPu. První řádky byly napsány někdy v říjnu 1999. Z počátku měl celý projekt sloužit jen k připomenutí a zdokonalení se v AutoLISPu. Časem ale vzniklo dost funkcí, které pokud by se poskládaly dohromady, byl by z toho celkem užitečný celek. První použitelné verze byly k dispozici v létě 2000. Spolehlivě fungovaly ale jen pod A2000. Skutečně spolehlivá verze byla až verze 1.40, o té se i přes všechny nedostatky dalo říci, že dělala, co měla. Celý program je napsán tak, aby sloužil jen jako pomocný nástroj, tj. aby příliš nediktoval styl práce a neomezoval svými nedostatky další práci. Doufám, že se to aspoň z části povedlo. Program obsahuje funkce na kreslení, kótování, popisování a pomocné funkce.

A modified version of XFLR5 (http://www.xflr5.com/xflr5.htm/) that focuses on analyzing a folder of airfoils to find the best airfoil for a given Re distribution Currently this project is very task-specific and may require a large amount of work to adapt it to other uses. It still has lots of bugs is definitely in its infancy. However, updates are planned for the future. Current Bugs of note: - The program doesn't currently close correctly. To close it you must use the task manager and end Qfils.exe

GeoPDEs is a suite of software tools for research on Isogeometric Analysis of PDEs. GeoPDEs is free software implemented in Octave and fully compatible with Matlab. GeoPDEs is no longer developed at SF, and has moved to GitHub. Please visit http://rafavzqz.github.io/geopdes/ The mailing list will remain active. Releases up to 2.0.4 can be found here. From version 2.1.0 onward, see https://github.com/rafavzqz/geopdes

CFD code using Arbitrary Lagrangian Eulerian algorithm.

Advanced Simulation Library (ASL) is a free and open source multiphysics simulation software package. Its computational engine is based, among others, on the Lattice Boltzmann Methods (http://en.wikipedia.org/wiki/Lattice_Boltzmann_methods) and is written in OpenCL (http://en.wikipedia.org/wiki/OpenCL) which enable extraordinarily efficient deployment (http://asl.org.il/benchmarks) on a variety of massively parallel architectures, ranging from inexpensive FPGAs, DSPs and GPUs up to heterogeneous clusters and supercomputers. The engine is hidden entirely behind C++ classes, so that no OpenCL knowledge is required from application programmers. ASL can be utilized to model various coupled physical and chemical phenomena and employed in a multitude of fields: computational fluid dynamics, virtual sensing, industrial process data validation and reconciliation, image-guided surgery, computer-aided engineering, high-performance scientific computing, etc..

FEDES is a Finite Element Data Exchange System for mapping finite element analysis data between different FE solvers and meshes with different element types and densities. Six commercial FE solvers are supported (ABAQUS, ANSYS, DEFORM, MARC, MORFEO, VULCAN). The FEA data outputted can be visualized with the open source program ParaView.

GeomSS is a geometry modeling and scripting system in Java. Write scripts that create and analyze complex geometry including NURBS curves and surfaces. This is especially useful for tasks that must be repeated with small or parametric variations.

The 1-dimensional gas-dynamics code. More information in http://www.openwam.com Modeling is an important technique for the optimization of internal combustion engines (ICE). The use of calculation models together with experimental tests is producing unquestionable successes due to the fact that both techniques complement each other. 1D wave action models simplify the engine by means of ducts, where only one dimension is considered, and volumes where mass accumulation is considered and the gas properties are uniform in the entire element. Finally, non dimensional models are used to solve connections between 1D and 0D elements. Thanks to more than 20 years, more than 10 PhD Thesis and many research projects and publications, CMT-Motores Térmicos has developed an own 1D gasdynamic tool called OpenWAMTM which gathers an important know-how on air management, compressible flow, turbocharging, chemical species tracking, numerical analysis and many other aspects of engine modeling.
