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.

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

Horizon EDA is an Electronic Design Automation package supporting an integrated end-to-end workflow for printed circuit board design including parts management and schematic entry.

Candle is a GRBL controller application with a visualizer for G-Code, the CNC programming language.

Supported functions include:

• Controlling GRBL-based cnc-machine via console commands, buttons on form, numpad.

• Monitoring CNC-machine state.

• Loading, editing, saving and sending of G-code files to CNC-machine.

• Visualizing G-code files.

WireViz is a tool for easily documenting cables, wiring harnesses and connector pinouts. It takes plain text, YAML-formatted files as input and produces beautiful graphical output thanks to GraphViz. It handles automatic BOM creation and has a lot of extra features.

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.

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

PrusaSlicer takes 3D models (STL, OBJ, AMF) and converts them into G-code instructions for FFF printers or PNG layers for mSLA 3D printers. It is compatible with any modern printer based on the RepRap toolchain, including all those based on the Marlin, Prusa, Sprinter and Repetier firmware. It also works with Mach3, LinuxCNC and Machinekit controllers.

Zydis is a decoder and disassembler library with the following features:

• Support for all x86 and AMD64 instructions and extensions

• Optimization for high performance

• No dynamic memory allocation

• Thread-safe by design

• Smaller file-size overhead compared to other common disassembler libraries

GPX is a post processing utility for converting gcode output from 3D slicing software to x3g files for standalone 3D printing on common 3D printers.

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

Gaf stands for “gschem and friends”. It is a subset of the entire tool suite grouped together under the gEDA name. gEDA/gaf is a collection of tools which currently includes: gschem, a schematic capture program; gnetlist, a netlist generation program; gsymcheck, a syntax checker for schematic symbols; gattrib, a spreadsheet programme that manipulates the properties of symbols of a schematic; libgeda, libraries for gschem gnetlist and gsymcheck; gsch2pcb, a tool to forward annotation from your schematic to layout using PCB; some minor utilities.

This package provides a C++ library for handling of multiple co-processes in cadabra.

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.

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.

This package contains binary data for Cura releases, like compiled translations. Prebuilt Firmware files are removed.

This package provides software that reads, writes, and modifies data in the CFD General Notation System (CGNS) format. The format is meant for recording and recovering computer data associated with the numerical solution of fluid dynamics equations. The format is a conceptual entity established by the documentation; the software is a physical product supplied to enable developers to access and produce data recorded in that format.

PyVISA is a Python package for support of the VISA, in order to control measurement devices and test equipment via GPIB, RS232, Ethernet or USB.

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.

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 contains the official KiCad footprint libraries.
