Hi,
is there any possibility, to solve a frequency response problem directly with the use of modal frequency information (EIGRL) as input, like the modal frequency response solution does?
The first mode is roughly at 300 Hz and therefore the modal solution in the range of 5 Hz is insufficient precise. But it is very important, to cover the resonant frequencies as well as the very low frequencies, which are very far from the resonant frequencies.
Thank you.
