Class HarmonicBC

Defined in Program listing for file kernel/src/modelingTools/HarmonicBC.hpp

class HarmonicBC : public BoundaryCondition

This class models a simple harmonic boundary conditions for prescribing the velocities in a Dynamical System.

A simple boundary condition is considered to fix a component \( j \) of the velocity vector, i.e., \( v_j(t) = a + b cos( \omega t+ \phi)\).
