Independant Mesh in Steady State Dynamic Analysis

[MohamedKhalil]

Good Morning,

I am a researcher in the field of geotechnical engineering. I used to use the FEA software COMSOL in analysis but now I am thinking about switching to Abaqus due to some technical problems. I just wonder if it possible to simulate friction between independent mesh parts in a steady state dynamic analysis to obtain the amplitude of motion over a specific range of frequencies.

Thank you in advance

That's mathematically not possible. Contact changes and friction are nonlinearities, but SSD is a linear procedure.

Thanks Mustaine3 for your kind response,

Is there any other way to simulate friction between two different parts without using an independent mesh so I can use the steady state analysis?
or is there any alternative to steady state analysis to obtain the amplitude of motion over a specific range of frequencies?

Will there be stick/slip changes? If not you can use linear constraint equations (tie or mpc).
