Meep is a finite-difference time-domain (FDTD) simulation software package developed at MIT to model electromagnetic systems.

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

VOLK contains procedures with machine-specific optimizations for mathematical functions. It also provides a machine-independent interface to select the best such procedures to use on a given system.

Iaito is the official graphical interface for radare2, a libre reverse engineering framework. Iaito focuses on simplicity, parity with commands, features, and keybindings.

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

PythonSCAD is a programmatic 3D modeling application. It allows you to turn simple code into 3D models suitable for 3D printing. It is a fork of OpenSCAD which not only adds support for using Python as a native language, but also adds new features and improves existing ones.

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.

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.

CuraEngine is an engine for processing 3D models into 3D printing instructions for Ultimaker and other GCode-based 3D printers. It is part of a larger project called Cura.

ADMS is a code generator that converts electrical compact device models specified in high-level description language into ready-to-compile C code for the API of spice simulators. Based on transformations specified in XML language, ADMS transforms Verilog-AMS code into other target languages.

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.

Area is a CAM-related software for pocketing operation.

This project provides library and associated python-module to compute pocket operations.

Kicad is a program for the formation of printed circuit boards and electrical circuits. The software has a number of programs that perform specific functions, for example, pcbnew (Editing PCB), eeschema (editing electrical diagrams), gerbview (viewing Gerber files) and others.

A restartable sequence is a critical region delimited by a program where if its execution is preempted or interrupted, the kernel will divert the program control flow to a defined abort handler. They are a good alternative to atomic operations for critical fast paths and are usually used in the context of per-cpu data. The library offers ABI headers to interface with the kernel and various utilities such as per-cpu counters.

MIT Photonic-Bands (MPB) computes definite-frequency eigenstates (harmonic modes) of Maxwell's equations in periodic dielectric structures for arbitrary wavevectors, using fully-vectorial and three-dimensional methods.

Libctl is a Guile-based library implementing flexible control files for scientific simulations.

Fastcap is a capacitance extraction program based on a multipole-accelerated algorithm.

This package contains the official KiCad 3D model libraries.

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

mbpoll is a command line utility to communicate with ModBus slave (RTU or TCP).

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

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

GNU LibreDWG is a C library to handle DWG files. It aims to be a free replacement for the OpenDWG libraries.

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