archibald 1.0.0 ⛵✏️
- 🐍 Archibald is a performance prediction package for sailboats and ships in the preliminary design stage. It is written in Python 3.
- 🎓 It is aimed in particular at naval architecture students. It is still under development, but its modules are now ready to be used independently.
- ✏️ In particular, Rhino and AutoCAD models and drawings can be directly imported for computation, giving an easy workflow to quickly assess the impact of design choices on performance, and play with it.
- Holtrop and Delft hull resistance method
- Built-in mesh-based hydrostatics
- Inviscid fluid-boundary layer coupling
- Sails computation with vertical wind gradient
- Planing hull resistance computation
- Post-stall aerodynamics model
Archibald 1.0.0 was widely used in the following student projects:
MOLENEZ II - Sailing general cargo ship for Ponant Islands feeding
Molenez II Render Molenez II Sail plan Molenez II Stability
NEREUS - Fast humanitarian aid vessel (tested in Centrale Nantes' towing tank)
Nereus render Nereus towing tank Nereus Stability
PAKI'AKA - Radical and high-performance bamboo 18ft skiff
Paki'aka render 1 Paki'aka render 1
Different examples of basic use can be found in /examples/:
- Hydrostatics and stability curve computation
- Hull resistance computation
- Appendage hydrodynamics computation
- Sails aerodynamics computation
