AuxKernels

• Fsi App
• WaveHeightAuxKernelCalculates the wave heights given pressures.

AuxVariables

BCs

• Fsi App
• FluidFreeSurfaceBCApplies a mixed Dirichlet-Neumann BC on the fluid surface.

InterfaceKernels

• Fsi App
• ADPenaltyVelocityContinuityEnforces continuity of flux and continuity of solution via penalty across an interface.
• CoupledPenaltyInterfaceDiffusionEnforces continuity of flux and continuity of solution via penalty across an interface.
• StructureAcousticInterfaceEnforces displacement and stress/pressure continuity between the fluid and structural domains. Element is always the structure and neighbor is always the fluid.

Kernels

• Fsi App
• AcousticInertiaCalculates the residual for the inertial force which is the double time derivative of pressure.
• ConvectedMeshCorrects the convective derivative for situations in which the fluid mesh is dynamic.
• ConvectedMeshPSPGCorrects the convective derivative for situations in which the fluid mesh is dynamic.
