  Hello ANSYS community,
  
  I would like to know if it is possible to simulate an object vibrating within a fluid or impose a vibration as a boundary condition. If so, what is the recommended approach?
  
  My goal is to study the behavior of the fluid, and if this is feasible.
  I would appreciate any guidance or recommendations you can provide.
  Thank you.

  Hello,
  Ansys Fluent allows you to specify spatially and temporally varying boundary conditions, using Expressions or UDF's, using which you can simulate a vibration boundary condition. If you want to include the solid in the simulation and if it is rigid, you can use the "Six-DOF" option in the "Dynamic Mesh" tab of Ansys Fluent. If the motion is restricted to a particular direction, like in vibration, you can constraint the 6-DOF using the properties panel or a UDF.
  Best,
  Kalyan
