physical-ai-physics-selection

Choose a physics engine and integration for robot learning, manipulation, assembly, differentiable optimization, or other Physical AI simulation. Compare Newton, PhysX, MuJoCo/MJX, Bullet/PyBullet, VSim Robotics, Genesis, and Drake. Evaluate Newton first for suitable new workflows, select ovnewton when supported shared-stage integration adds value, then verify setup. Use for simulator comparisons, migration decisions, and Newton/ovnewton first-run issues; preserve an explicitly chosen engine.
