Hello dear all

I want to simulate the fatigue under sine acceleration. So before the setting of vibration fatigue, which former simulation should i do? frequency domain ,time dependent or stationary study? And then what should be setted in the vibration fatigue? Comsol informed me "The load cycle is not frequency controlled." How can i add the frequency to the load directly?

thank you for your attention!

Best regards Xiaohui

Dear Xiaohui,

Are you passing the study into the fatigue module? As in you could run a stationary and use the intiial values for the fatigue module and set your break down criterion such as S-N curve etc.
