  The formulation of a canonical deep-water breaking wave problem is
introduced, and the results of a set of three-dimensional numerical simulations
for deep-water breaking waves are presented. In this paper fully nonlinear
progressive waves are generated by applying a normal stress to the free
surface. Precise control of the forcing allows for a systematic study of four
types of deep-water breaking waves, characterized herein as weak plunging,
plunging, strong plunging, and very strong plunging.
