BRL-CAD is a constructive solid geometry (CSG) solid modeling computer-aided design (CAD) system. It includes an interactive geometry editor, ray tracing support for graphics rendering and geometric analysis, computer network distributed framebuffer support, scripting, image-processing and signal-processing tools. The entire package is distributed in source code and binary form. BRL-CAD is a powerful cross-platform Open Source combinatorial Constructive Solid Geometry (CSG) solid modeling syst
Qucs-S is a circuit simulation program based on Qucs circuit simulator. The "S" letter indicates SPICE. The purpose of the Qucs-S project is to use free SPICE circuit simulation kernels with the GUI based on Qt toolkit. It merges the power of SPICE and the simplicity of the Qucs GUI. Qucs-S is not a simulator by itself, but it requires to use an external simulation backend with it. Qucs-S allows to use the following open-source simulation kernels: Ngspice is recommended to use. Ngspice is powe
OPENMODELICA is an open-source Modelica-based modeling and simulation environment intended for industrial and academic usage. Its long-term development is supported by a non-profit organization – the Open Source Modelica Consortium (OSMC). An overview journal paper is available and slides about Modelica and OpenModelica. The goal with the OpenModelica effort is to create a comprehensive Open Source Modelica modeling, compilation and simulation environment based on free software distributed in b
CadQuery is an intuitive, easy-to-use python based language for building parametric 3D CAD models. CadQuery is for 3D CAD what jQuery is for javascript. Imagine selecting Faces of a 3d object the same way you select DOM objects with JQuery!
