Hi all

I need to get the Mass Properties (CoG,MoI) for my Model in tabular form in my out file. I also need the effective mass for each mode in a tabular form. How do I get these tables in my Optistruct .out file. Thank you for any help:-)

    effective mass is output using PARAM,EFFMASS or something like this.

    It will write mass participation in your .out file and in some other auxiliary file that I can't remember the name right now.

     

    Mass and CoG I can't recall from the top pof my head, but certainly you can, by using some PARAM card, i think.
