Hi,

How can I input this equation as a wall motion equation ?!

(Time vs displacement curve)

Thanks in advance

Hello, nYou can use either Time varying Transient profiles or UDF to provide this profile information.nYou will find more information on Transient Profiles here [https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v202/en/flu_ug/flu_ug_sec_bcs_transient.html]nAlso, please make sure that the wall motion that you want to specify is purely tangential to the wall surface. If you have any normal component to the wall surface, then consider using a sliding mesh or dynamic mesh approach.nMore information can be found in the following link.nI hope this helps.nRegards,nSuryan
