  • Is there some kind of CAD program you can design Mujoco MJCF XML files in?
    The most famous and complete free sim for actual natural body parts is https://simtk.org/projects/opensim. Source: over 2 years ago
  • How to use Motion Capture Data on OpenSim - Help!
    Hi, I take it you're meaning opensim which models musculoskeletal structures and creates dynamic simulations of movement rather than opensimulator. Source: over 2 years ago
  • Ask HN: What problem are you close to solving and how can we help?
    My research specialty is biomechanics. For the arm motion thing, it sounds like you might want inverse kinematics or inverse dynamics. Take a look at OpenSim: https://simtk.org/projects/opensim For the oral appliance adjustment, I'm not sure what your output measures of interest are. If they're mechanical maybe you want to do a sensitivity analysis using FEA. Maybe look at FEBio: https://febio.org/ As for... - Source: Hacker News / over 2 years ago
  • OpenSim issues
    The first link you shared doesn’t take me to the same spot I downloaded the models from. This link: https://simtk.org/projects/opensim should take you to the home site.
