Error originates in Mechanical block StewartPlatform/BasePlant/Leg2/Leg Cylindrical. The motion is singular (the mass matrix is singular). Check the mass properties and joint axes of the attached bodies.
During Stewart platform simulation, I encountered the above error. Does anyone know how to resolve it?
Thank you!

Make sure the mechanism is not over-constrained. Add inertia between two connected joints.
