adding move to the fluid-solid interface

I am trying to simulate an elastic solid moving in a fluid domain. The fluid solid interface boundary has a defined movement. How to achieve this? Do I need to add other module except for the fluid structure interaction?
very grateful if anyone has any suggestions.

Hi Gengyun Li
Have a try with this tutorial: www.comsol.ch/model/particle-t...g-in-a-micromixer-12151
which is rigid - this is the meaning of the fluid-solid boundary has a defined movement (a.k.a prescribed displacement). Later you can try to add elasticity, i.e. have a feedback of the fluid forces on the solids if necessary.
Best regards,
Sven Friedel

Dear Sven,
The linkage you provided is invalid at present. The discussion topic is precisely what I am concerned about. For most FSI example in manual, the outer boundary for all domains are fixed. If the outer boundary is moving, i.e. the solid boundary, as a part of outer boundary, is deformed under exterior loading. How to prescribe this kind of boundary condition for ALE equation in FSI module.
Thanks,
Zeng
