Modal Analysis

Post by AmirAkhavani » Thu Dec 20, 2018 4:46 am

Hi everybody
How can I get eigens (modes) after each step of analysis?
Normally, when we use eigen command before analysis command, we get modes of free vibration in initial model while we want to get modes in deformed shape of structure for each iteration.
