[SOLVED] DYNAMIC ANALYSIS loadings

Hello,

I'm performing a DYNA_VIBRA analysis (BASE_CALCUL='PHYS' , TYPE_CALCUL='HARM').

My question: is it possible to load the model applying harmonic nodal accelerations (or displacements), instead of nodal forces?

I haven't found this possibility in the manual U4.44.01 (AFFE_CHAR_MECA).

Thanks in advance,
Lluis

How about AFFE_CHAR_MECA_F for nodal displacements ?

Hi dbpatankar,

Thank you very much for your advice. I didn't realised there is DDL_IMPO option in AFFE_CHAR_MECAx.

Best regards,
Lluis
