OCCT: Open Source 3D Modeling and Simulation Software
An open source software for 3D modeling, simulation, CAD modeling, meshing tools, and structural analysis using the finite element method.
What is OCCT?
OCCT (Open Cascade Community Edition) is an open source software for 3D modeling, data exchange, and simulation. It is developed and maintained by Open Cascade SAS, with support from a community of contributors.
For CAD, OCCT includes modeling kernels and application frameworks for developing CAD/CAM/CAE applications. It supports NURBS and B-rep modeling as well as data exchange with popular formats like STEP and IGES. The CAD modules focus on mechanical engineering applications.
On the simulation side, OCCT provides meshing tools and solvers for finite element structural analysis. This allows for performing tasks like static stress analysis, vibration analysis, and thermal analysis. The simulation modules are built to integrate with the CAD environment for easier multiphysics workflows.
Some of the notable features of OCCT are advanced solid modeling tools like fillets and booleans, optimized meshing algorithms, multi-threaded solvers for faster simulations, and data visualization for analysis results. The modular architecture also allows customizing OCCT by developing plugins and addons.
Overall, OCCT is a good open source alternative to commercial CAD/CAE software for engineering design and analysis with mechanical applications. The source code access allows customization for specific use cases as well. It can be a cost-effective solution for small businesses, academic researchers, and hobbyists.
