Hello and thank you for your answer. My system is linear so i tried to run the analysis with the standard mode (the one presented in the section 63.11). But my problem occurs when i have to define the PSD spectrum. I do not know how to fill the data table. I have the power spectral density that means that i know the PSD related to a specific frequency (for example between 20Hz and 100Hz i have a PSD equal to 0.0044g2). But i don't know how to find the real part and the imaginary part Abaqus is asking me for each frequency. Do you think it's correct to only fill the real part ? Thank you, Clement
