dynamic simulation : parts are grounded

[Anonymous]

In Inventor Fynamic simulation, all my parts are grounded, when i create a standard joint manually, the software automatically supresses the joint and says cant create joints between fixed parts. Tried both revolute and cylindrical. just a hinge joint i try to create. the part to which i try to create is not fixed, i can move the same in assembly. where as once i come to dynamic simulation environment, its grounded and does not move into the mobile groups. what could be the problem. Can any one tell me whats the actual problem.

Try this in DS environment:

Simulation Settings: Uncheck "Automatically Convert Constraints to Standard Joints"

You can maintain already created Joints. If needed, they can be suppressed.

After that you can apply your own Joints. If needed, an option for unwelding groups is available by right-click in DS browser.
