Dynamic Boundary Condition. Viscous boundary, which was first proposed by Lysmer and Kuhlemeyer [32], is adopted as the boundary condition of the model.
Two boundary conditions must be imposed on the free surface, namely the kinematic boundary condition and the dynamic boundary condition. The kinematic boundary condition states that the fluid particles on the free surface move always along the surface, i.e.,
The dynamic boundary condition describes the continuity of the stress at the free surface, i.e.,
As an application, we prove the existence of exponential attractors for the reaction-diffusion equation with dynamic boundary condition.

If the sinusoidal pulse was short (close to a single period), it would become compressed in propagation if the dynamic boundary condition was [sigma](0, t) ~ + sin and stretched if [sigma](0, t) ~ - sin.
We consider the asymptotic behavior of solutions to the following parabolic equations with dynamic boundary conditions and irregular data,
Differential operators in the solution structures transmit information about the dynamic boundary conditions from the boundary to the domain.
So, it is necessary to construct a dynamic interval wavelet in solving the PDEs with dynamic boundary conditions such as the fractional PDEs.
In the interface-tracking methods, the free surface is treated as a boundary of the computational domain, where the kinematic and dynamic boundary conditions are applied.
