The development of a robust computational algorithm
suitable for modeling the motion of the three-dimensional
interface between air, water and a floating structure is
described. The algorithm uses an advanced data structure to
define the free surface interface as a series of nodes joined to
an arbitrary number of other nodes located on the interface.
Each node-node connection is defined uniquely as an edge,
and the overall surface as a series of patches constructed from
an arbitrary number of edges. Continuity of surface gradient
and curvature at each node is determined via an iterative
procedure. Once calculated this provides sufficient end
conditions to define each edge as a parametric cubic spline and
each patch as a combination of 3 and/or 4 edge bi-cubic
patches. An identical data structure defines the surface of the
floating structure. Nodes at the intersection between the
floating structure and free surface are accurately tracked over
the actual surface of the structure through knowledge of its
local gradient and curvature.
