Reply To: Apply a moment in Explicit Dynamics

[Chris Quan]

I tested Explicit Dynamics system in ANSYS 2024R2. I am able to create a Revolute Joint and use Joint - Moment to rotate the parts. See the screen snapshots below of the model setup and the results.

You need to set the Hourglass Damping in Damping Controls under Analysis Settings to Flanagan Belytschko to minimize the hourglass energy from rotational motion if HEX elements are used.

You also need to check contact setup under Connections to make sure there is no bonded contact generated on the joint interface.
