How to prescribe a forcing pressure gradient condition in the momentum equation (CFD)

Please login with a confirmed email address before reporting spam

Hi,

I am solving a FSI problem using oscillatory fluid flow which deforms a solid attached inside a pipe . To get an oscillatory flow, I need to prescribe a forcing pressure gradient condition in the momentum equation. Can someone please guide me on how is it done in COMSOL? Should it be done by replacing external force term of the Navier Stoke's equation? If yes, then how can I do that?

Thanks.
