We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hello Zhao,

Which element type and elform are you using for the blank? Is it shell elements? Or solids? What material are you using for the blank? Do the element type and elform and material model for the blank remain the same when the rotating wheel speed is 628 rad/min and when it is 3140 rad/min?

Have you checked your energy summary? Plot internal energy, kinetic energy, hourglass energy, and sliding energy together from the GLSTAT database and attach a screenshot here on this Forum post. Do you see any anomalies? Hourglass issue? Contact issue? 

Is the wheel modeled as rigid?

 

Reno.
