frequency response analysis

Hi to everyone

 

I m analyzing frequency response analysis. i have a small doubt . using DAREA card we apply load in constraints and forces in analysis section is also used to apply load . what is the different between these two . how it will affect on result .

 

thanks

DAREA is for dynamic loads whereas FORCE1 and FORCE 2 is for static loads.

Combinations of dynamic loads (DAREA) with static loads (FORCE, FORCE1, FORCE2, MOMENT, MOMENT1, MOMENT2, PLOAD, PLOAD1, PLOAD2, PLOAD4, and RLOAD), is supported.
