Here is my question: I would like to observe, through the Flow Simulation module, the reaction of the air following a translational movement in a cavity.
Let me explain. A rigid plate, mounted on a rubber bellows, and fixed on a cavity and will be subjected to a frequency (see attached image). When it moves, the airflow in the cavity will be modified and I would like to observe this result. It's a bit like a loudspeaker, when its diaphragm vibrates it displaces air.
In the parameters of the Flow Simulation study, it is possible to indicate the presence of gravity or a rotational movement (fan) but nothing about a translational movement.
--> How can we simulate this movement and observe the result?
A rotation of very large radius and very small amplitude could be assimilated to a translation. But does SW generate an oscillatory rotational movement?
I found the answer by myself, a site makes a reference of what is possible or not with SolidWorks Flow Simulation:

What Flow Simulation can do
Incompressible (liquid or gas) or compressible (gas) viscous flow including subsonic, transonic and supersonic regimes
External and/or internal flows
Non-Newtonian Flows (Viscous fluids such as blood)
Automatic laminar/turbulent solution with transition
Wall roughness model
Swirling flows and fans (fan curves)
One component or up to ten independent species -liquid-liquid mixing, or gas-gas mixing
Forced, free or mixed convection – heat transfer
Conjugated heat transfer (fluid, solid), conduction and convection
Porous Media
Radiation
Steady state and Transient (time-dependent) fluid flow
Rotating Frames of Reference
TEC coolers/heat sink emulators/Thermostats
Cavitation
Relative Humidity
What Flow Simulation cannot do
Phase Change - The Flow package cannot handle materials cooling and transforming from gas-to-liquid, or molten liquid-to-solid. Similarly, it cannot handle materials heating from molten solid-to-liquid, or liquid-to-gas. This requires special high-end, non-linear and complex formulations, specifically for modeling, entropy and chemical/molecular changes to account for cool, down, etc. Eg: plastic flow throw an injection mold as it cools and solidifies.
Co-existence of different phases – Flow Simulation cannot simulate a liquid and a gas in the same cavity. For instance, water flowing out of a nozzle into air (since water and air exist in the same cavity after the water flows out). Similarly, sprays (where fluid bubbles are sprayed into air). Different fluids (liquids/gases) can co-exist in a Flow Simulation if they exist in different cavities or volumes.
Free Surface Phenomena – Flow Simulation cannot simulate the top layer of a liquid sitting in an open tank. This again requires highly non-linear and complex formulae that are characteristic of high-end packages.
Moving bodies - Flow Simulation cannot simulate bodies moving and displacing fluids as they move. This requires special high-end focused packages that can handle Fluid-Structure-Interaction (FSI).
Combustion – Flow Simulation cannot perform chemical reactions to account for combustion.
Particles/Suspensions – Flow Simulation cannot simulate solid/liquid suspensions in a fluid where the suspensions can influence the pattern/parameters of flow. Since Flow Simulation cannot have two different phases in the same volume, it does not support solid particles in a fluid stream/liquid particles in a fluid stream/gas trapped in a liquid stream etc. ''
