Reply To: Unexpected Periodic Deformation in 2-Way FSI Simulation with Constant Inlet Velo

[idenyu8701]

How can I ensure that the boundary conditions are reasonable?

For the fluid domain:

• Inlet velocity: 0.5 m/s
• Outlet: pressure outlet
•  glycerin

For the structural domain:

• Object: a rectangular block
• Boundary condition: Fixed support at the bottom, while other surfaces are set as fluid-solid interface

Is this setup appropriate?
