Detailed Description

GeomObject representing a vertical leaflet that performs bending and stretching oscillations.

Constructor & Destructor Documentation

Leaflet()

Leaflet::Leaflet ( const double &  length, const double &  d_x, const double &  d_y, const double &  x_0, const double &  period, Time *  time_pt  )

inline

Constructor: Pass length (in Lagrangian coordinates), the amplitude of the horizontal and vertical deflection of the tip, the x-coordinate of the origin and the period of the oscillation. Passes the number of Lagrangian and Eulerian coordinates to the constructor of the GeomObject base class.

  : GeomObject(1,2), Length(length), D_x(d_x), D_y(d_y), X_0(x_0),
   T(period),Time_pt(time_pt) {}
