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.

pandapower is an easy to use network calculation program aimed to automate the analysis and optimization of power systems. It uses the data analysis library pandas and is compatible with the commonly used MATPOWER / PYPOWER case format. pandapower allows using different solvers including an improved Newton-Raphson power flow implementation, all PYPOWER solvers, the C++ library solvers for fast steady-state distribution power system analysis of PowerGridModel, the Newton-Raphson power flow solvers in the C++ library lightsim2grid, and the PowerModels.jl library.

Lib3MF is a C++ implementation of the 3D Manufacturing Format (3MF) file standard. It offers a way to integrate 3MF reading and writing capabilities, as well as conversion and validation tools for input and output data. The specification can be downloaded at http://3mf.io/specification/.

esptool.py is a Python-based utility to communicate with the ROM bootloader in Espressif ESP8266 & ESP32 series chips.

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 the official KiCad footprint libraries.

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.

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

LibCharon is a Python file metadata and streaming library. It belongs to the Cura project from Ultimaker.

libmodbus is a library to send/receive data with a device which respects the Modbus protocol. This library can use a serial port or an Ethernet connection.

This library contains C++ code and Python3 bindings for creating a socket in a thread and using this socket to send and receive messages based on the Protocol Buffers library. It is designed to facilitate the communication between Cura and its backend and similar code.

LinSmith is a Smith Charting program, mainly designed for educational use. As such, there is an emphasis on capabilities that improve the 'showing the effect of'-style of operation.

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

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

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.

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

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.

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.

Uranium is a Python Framework for building 3D printing related desktop applications using PyQt5. It belongs to the Cura project from Ultimaker.

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

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

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.

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.

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.
