    Hello,

     

    typically a subcase for eigenfrequency analysis looks like this...

     

    SUBCASE       1
      LABEL EIQFR
      SUBTITLE  = EIQFR
      ANALYSIS MODES
      METHOD(STRUCTURE) =  4
     

    with the corresponding EIGRL card, e.g (number = 4 in this case)

     

    EIGRL          40.1     50.0          10                            MASS
     

    It seems that in your deck some entrys are still missing.

     

    Regards,

    Mario
