the frequency response

[wshrr]

Hi everyone

I’m modeling a Rubber ring and on the top is the steel. I’m following the tire example analysis to find the frequency response. So I have three steps. In the last step I want to see the frequency vs disp. I got an error massage as you can see in the attachment. I really appreciate any help.

I don't think I have seen that error before. What types of load steps are you applying?

thank you

The Load step in the step 3"dynamic step" is harmonic.thank you for your help.
