Did you try using step : Linear perturbation > Frequency.

You can specify frequency range and monitor displacement at particular node in output

Thanks Dhaval for your reply.

I have tried linear perturbation-frequency step, even i have given my frequency range, but  i am not able to see any vibration in the specimen.

could explain me how can approach?

thanks and regards,

Hallo Dhaval,

Could you please, tell me how to monitor diaplacement at particular nodes in output.

Thanks and regards,

Hello Avuku,

you can use field output history with unique node configuration and monitor displacement of node.

Hey hi guys,

I want to know what is linear perturbation?

What does it mean?n how it works?

Hi Rutuja,

Linear analysis means that the behavior of material is linear.  If the material behavior is non-linear, then the property can be linearized for stressed or unstressed structure. This is called perturbation.
