Rotational Modal Effective Mass and Coord.Sys Definition

Dear Code_Aster users,

I would like to calculate rotational modal effective mass, but I don't know how to perform this?
Anyone of you have any suggestion?

In Nastran code, this output is related to orientation and coord.sys origin definitions: how could I set it?

For translational effective mass, I use this command:

IMPR_RESU(identifier='11:1',

          FORMAT='RESULTAT',

          MODELE=model,

          RESU=_F(FORM_TABL='EXCEL',

                  NOM_PARA=('FREQ', 'MASS_EFFE_DX', 'MASS_EFFE_DY', 'MASS_EFFE_DZ'),

                  RESULTAT=modes,

                  TOUT_CHAM='NON'),

          UNITE=8)




I attach mesh and .comm file.

All the best,
S
