Hello,

Are you trying this FSI study with intrinsic FSI model available in Fluent or Fluent-Mechanical coupling?
Regarding wall deformation and oscillation, please check your dynamic mesh inputs. Allow the wall to receive the displacement and fluid domain to deform as per the deformation of wall.

Please refer to the FSI tutorials available here: Reed Valve FSI Co-Simulation with Partial Setup Export from Workbench (Fluent-Mechanical) (ansys.com), Chapter 27: Modeling One-Way Fluid-Structure Interaction (FSI) Within Fluent (ansys.com) and Chapter 28: Modeling Two-Way Fluid-Structure Interaction (FSI) Within Fluent (ansys.com).

Hope this helps!
