What the maker publishes
- Analysis and automation
- The C++ API exposes GUI functionality to programs and supports headless modeling and analysis, external software integration, trade studies, and optimization automation. source
- API languages
- Official API documentation provides C++, AngelScript, and Python resources, and lists MATLAB API examples in the distribution. source
- API limitation
- The Python API version must match the Python version OpenVSP was compiled with; using another version requires compiling OpenVSP yourself. source
- CAD export
- The 3.54.0 release adds split and stitched STEP and IGES export and says every CAD export path is tested by reading the file back with OpenCASCADE. source
- Community support
- The project directs users to the VSP Google Group for discussion and offers a GitHub issue tracker for bug reports and feature requests. source
- File import and export
- STL, IGES, SVG, NASCART, V2, BEM, VSP3 source
- Founded
- 2012 source
- Free plan
- Yes source
- Geometry cloning
- The 3.54.0 release adds Clone geometry for duplicating components when symmetry is insufficient. source
- Intended users
- The project describes its users as aircraft designers and invites users to contribute models, test releases, improve documentation, answer mailing-list questions, and develop software. source
- Learning resources
- The project provides tutorial videos through OpenVSP Ground School and technical documentation through its Wiki and API documentation. source
- Meshing
- The 3.54.0 release describes CFDMesh as faster, multithreaded, more robust, and producing higher quality output. source
