We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

The 3D model has elements with a high aspect ratio which tends to degrade into an hourglass mode which ultimately leads to a failure to converge. I could not improve the aspect ratio within the limits of the Student license, but if you have a full license, you can improve the aspect ratio and the simulation may continue solving for a larger displacement.
