FreeCAD is a general-purpose, feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE, and PLM. It is aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is modular, allowing for extension and customization.

This package provides a pipeflow calculation tool that complements pandapower in the simulation of multi energy grids.

Manifold is a geometry library dedicated to creating and operating on manifold triangle meshes. A manifold mesh is a mesh that represents a solid object, and so is very important in manufacturing, CAD, structural analysis, etc.. Manifold also supports arbitrary vertex properties and enables mapping of materials for rendering use-cases.

This package provides a computer algebra system geared towards field theory.

OpenCTM is a file format, a software library and a tool set for compression of 3D triangle meshes. The geometry is compressed to a fraction of comparable file formats (3DS, STL, COLLADA...), and the format is accessible through a simple API

poke-elf is a GNU poke pickle for editing ELF object files, executables, shared libraries and core dumps. It supports many architectures and extensions.

This library provides functionality for shape modelling, visualization, matrix manipulation.

Cura is a slicing software from Ultimaker. A slicer generates G-Code for 3D printers.

Fasthenry is an inductance extraction program based on a multipole-accelerated algorithm.

This is a minimalist terminal program like minicom or cu. The only thing it does is creating a bidirectional connection between stdin/stdout and a terminal device (e.g. serial line). It can also set serial line baudrate, manipulate DTR/RTS modem lines, send break and throttle transmission speed.

MeshLab is a system for the processing and editing of large, unstructured, 3D triangular meshes. It is aimed to help the processing of the typical, not-so-small unstructured models arising in 3D scanning, providing a set of tools for editing, cleaning, healing, inspecting, rendering and converting this kind of meshes. These tools include MeshLab proper, a versatile program with a graphical user interface, and meshlabserver, a program that can perform mesh processing tasks in batch mode, without a GUI.

Libnest2D is a library and framework for the 2D bin packaging problem. It was inspired from the SVGNest Javascript library.

This package provides a computer algebra system geared towards field theory. This package is mostly meant to be used by texmacs and mogan.

Harminv is a free program (and accompanying library) to solve the problem of harmonic inversion — given a discrete-time, finite-length signal that consists of a sum of finitely-many sinusoids (possibly exponentially decaying) in a given bandwidth, it determines the frequencies, decay constants, amplitudes, and phases of those sinusoids.

The purpose of the MED module is to provide a standard for storing and recovering computer data associated to numerical meshes and fields, and to facilitate the exchange between codes and solvers.

The persistent data storage is based upon HDF format (like CGNS, a standard developed by Boeing and NASA in the area of Computational Fluid Dynamic).

MED also provides structures to hold data on meshes and fields. These structures are exchanged between solvers, hide the communication level (CORBA or MPI), and offer persistence (read/write in .med files).

The main benefit of a common exchange format is reduced complexity of code coupling. It also allows sharing such high level functionalities as computation of nodal connectivity of sub-elements (faces and edges), arithmetic operations on fields, entity location functionalities, and interpolation toolkit.

Valeronoi (Valetudo + Voronoi) is a companion for Valetudo for generating WiFi signal strength maps. It visualizes them using a Voronoi diagram.

GNU poke is an interactive, extensible editor for binary data. Not limited to editing basic entities such as bits and bytes, it provides a full-fledged procedural, interactive programming language designed to describe data structures and to operate on them.

This package contains CPython bindings for libnest2d-for-cura.

This package contains all part definitions that are required for Fritzing app.

Radare2 is a complete framework for reverse-engineering, debugging, and analyzing binaries. It is composed of a set of small utilities that can be used together or independently from the command line.

Radare2 is built around a scriptable disassembler and hexadecimal editor that support a variety of executable formats for different processors and operating systems, through multiple back ends for local and remote files and disk images.

It can also compare (diff) binaries with graphs and extract information like relocation symbols. It is able to deal with malformed binaries, making it suitable for security research and analysis.

SOLVESPACE is a parametric 3D CAD tool. Applications include:

• modeling 3D parts — draw with extrudes, revolves, helixes and Boolean (union / difference / intersection) operations

• modeling 2D parts — draw the part as a single section, and export DXF, PDF, SVG; use 3D assembly to verify fit

• 3D-printed parts — export the STL or other triangle mesh expected by most 3D printers

• preparing CAM data — export 2D vector art for a waterjet machine or laser cutter; or generate STEP or STL, for import into third-party CAM software for machining

• mechanism design — use the constraint solver to simulate planar or spatial linkages, with pin, ball, or slide joints

• plane and solid geometry — replace hand-solved trigonometry and spreadsheets with a live dimensioned drawing

Capstone is a lightweight multi-platform, multi-architecture disassembly framework. Capstone can disassemble machine code for many supported architectures such as x86, x86_64, arm, arm64, mips, ppc, sparc, sysz and xcore. It provides bindings for Python, Java, OCaml and more.

The libspnav library is provided as a replacement of the magellan library. It provides a cleaner, and more orthogonal interface. libspnav supports both the original X11 protocol for communicating with the driver, and the new alternative non-X protocol. Programs that choose to use the X11 protocol, are automatically compatible with either the free spacenavd driver or the official 3dxserv, as if they were using the magellan SDK.

Also, libspnav provides a magellan API wrapper on top of the new API. So, any applications that were using the magellan library, can switch to libspnav without any changes. And programmers that are familiar with the magellan API can continue using it with a free library without the restrictions of the official SDK.

This package provides a utility for converting Kicad (.mod, .lib), Eagle (.lbr), gerber (.gbr, etc..), BXL (.bxl), IBIS (.ibs), symdef, LT-Spice (.asc), QUCS (.sch), and BSDL (.bsd) symbols and footprints and EggBot fonts to gEDA.
