Yes, that's correct, see my small models in the shells thread I linked above.
Also, do the check on statics with 6 unit loads, 6 loadcases: 3 Forces & 3 moments, one load per DoF.
By isolating the inputs per DoF you know what you should get on the 3 moments LCs in the tied pairs table sum and all reactions sum. It's a quick check I do in all assys. I've seen free-free modals to work, and then the moments sum reactions to be out in statics; different solvers.
Code_aster seems to have theoretical checks on both statics and modal; I ignore them all and turn defaults off so the job doesn't stop. If it is a wrong setup, I want to 'see' it on the actual results, and not a theory algo to tell me it is wrong.
Just seen in your table that mode#6 (labeled 7) is at 43Hz, not good if it was a free-free modal.
