 # Capabilities of HydroChrono
 
 With HydroChrono, you can model any system that's supported by Chrono - from multiple bodies and joints to finite element bodies and discrete element particles. HydroChrono will supply hydrodynamic forces to any rigid body in the system - whether you're looking to simulate multibody wave energy converters (WECs) or floating offshore wind turbines (FOWTs) with flexible towers and blades through Chrono::FEA.
