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.

Hi Hamderson,


 


So you don't have a constraint on the model and it is subjected to rigid body motion. You can tell by looking at the mode frequencies, there are 0s. Please apply a boundary condition and see.
