When fluids move extremely slowly (high viscosity, low inertia), the non-linear terms in the Navier-Stokes equations drop out. FEA handles these "linear" viscous problems very well (e.g., polymer extrusion, glass forming, lubrication).
For an incompressible fluid, the divergence of the velocity vector field must be zero: ∇⋅u=0nabla center dot bold u equals 0 is the fluid velocity vector. 2. Momentum Conservation fea fluid dynamics
"FEA Fluid Dynamics" is effectively . While not the industry standard for pure aerodynamics or hydrodynamics (where FVM reigns), it is the dominant method for simulating how fluids interact with and deform solid structures (FSI). When fluids move extremely slowly (high viscosity, low
Fluids are highly non-linear. You almost always need an . lubrication). For an incompressible fluid
