Hi. I am modeling a two-way fluid-solid interaction, a backward-facing step using an oscillating fin to capture its secondary vortices. I want to set v= aw sin(wt) with defined values of a and w and give this velocity to a vertical fin installed in the top wall of this channel. I want to know what steps should I take to give an oscillating velocity to this fin?June 21, 2021 at 8:03 am1shanAnsys EmployeeIs the oscillating flap rigid or is it flexible? If its a rigid body then I don't think a 2 way FSI would be needed you could use a dynamic mesh in fluent(" target="blank">). If its flexible then you can insert a remote displacement scoped to the geometric entity you want to oscillate and define the magnitude as a function of time ( ex: sin(100*time)).

So, whenever the deformation of the solid body impacts the fluid zone, and the fluid applies force to the solid, a two-way FSI will be needed. If the solid deforms, should I use the velocity support (instead of a fixed one) and define the oscillating velocity?
