Fluid Boundary Conditions for Hose Simulation: Pressure Inlet/Outlet, Coupled Surface, and Deforming Boundary

The fluid's inlet and outlet boundaries are designated as 'pressure inlet' and 'pressure outlet', respectively. The fluid's outer surface is configured as a 'coupled boundary' to transmit force data to the hose's inner surface. The fluid's deformable boundary is set as symmetrical so that it can deform in conjunction with the coupling wall.
