[Product Introduction] Hyfydy | Bio-motion and musculoskeletal simulation tool

On the Unipos website, a high-performance biomechanics simulation software "Hyfydypage has been added.

Hyfydy is a musculoskeletal (biomechanical) simulation software that combines high accuracy with fast simulation speed.

Hyfydy boasts high accuracy with the same high-quality muscle and contact models as OpenSim 2019, and simulation speed equivalent to MuJoCo (100 times faster than OpenSim).OpenSim Accuracy"When"MuJoCo Simulation Speed" It has the performance to combine.

Additionally, an error-controlled integrator allows automatic adjustment of step sizes based on user-defined accuracy, ensuring both accuracy and stability.

Main uses and features of Hyfydy

• Biomechanics Analysis
• Muscle model simulation
• High-precision contact model
• Machine Learning Integration
• Real-time analysis

Hyfydy is available as a plugin for SCONE* and also via a Python API for machine learning applications.

About SCONE

Open source software for predictive simulation of biological motion. You can define and optimize neuromuscular controllers to optimally perform specific tasks, such as walking speed and energy efficiency. SCONE is available for Windows, Linux and macOS.

Comparison information for Hyfydy / MuJoCo / OpenSim

Comparison of Hyfydy and MuJoCo

• Hyfydy's muscle model Tendon ElasticityAccurately simulating this allows for important mechanisms of energy storage and release in biomechanical systems (MuJoCo does not model this phenomenon)
• Hyfydy contact forces are realisticNonlinear Damping, which supports dynamic and viscous friction coefficients (contact in MuJoCo does not model these properties)
• In HyfydyError Control IntegralWe use a fixed step size integration with no error control, adjusting the integration step size to ensure robustness and consistent simulation accuracy.

Comparison of Hyfydy / MuJoCo / OpenSim

• Hyfydy is Opensim We use the same muscle and contact models as in 2019.
• Hyfydy and MuJoCoSimilar speedBoth are orders of magnitude faster than OpenSim.
• Both Hyfydy and MuJoCoCollision detection, and responds across a wider range of collision primitives compared to OpenSim's limited collision detection support.
• Both MuJoCo and OpenSimfree and open sourceHowever, Hyfydy is proprietary, paid software.
