Hello, probably there are several elements which show high stress (higher than the stress at the 1st point on the SN curve). Are you using *FATIGUE_ELOUT? Can you remove those elements (not nodes) from *DATABASE_HISTORY_SOLID (or SHELL) and try again? *FATIGUE_ELOUT only computes fatigue damage for the elements included in binout. Thanks.
