Coupling Fluid-Structure Interaction with Free and Porous Media Flow

Please login with a confirmed email address before reporting spam

Hi all,

I am looking to use the Fluid-Structure Intereaction multiphysics (comprised of laminar flow and solid mechanics) with a porous structure. I have been trying to couple Free and Porous Media Flow interface with the Fluid Structure Interaction, but perhaps I would be better to use the Brinkman Equations to couple with the Fluid-Structure Interaction?

Whenever I try to use these different physics together, I my solve fails to converge for the first time step.

Any help would be greatly appriciated.

Kind regards, J
