@Orel,
I believe that a harmonic analysis is somewhat of a forced response. You apply a cyclic load to the structure, sweep through a given excitation frequency range and obtain the displacements as a function of time for each load step. It's a nice way to obtain a frequency response curve.

Thank you for the response Drej.
You are correct in the sens that modal displacements are only relative. Which is why their actual value is not of interest but their variation during the period studied. There is not a particular forcing involved, it would be just a way to better characterize...
Hi,
I am new to this forum and was wondering if you could help me out.
I am running a modal analysis of a cyclic symmetric structure (only one sector is meshed and the analysis is ran using CYCLIC option of /PREP7). Once the analysis is done, you can recompose double harmonics or nodal...
