Query: Efficient computation of capillary-gravity generalized solitary waves   This paper is devoted to the computation of capillary-gravity solitary waves
of the irrotational incompressible Euler equations with free surface. The
numerical study is a continuation of a previous work in several points: an
alternative formulation of the Babenko-type equation for the wave profiles, a
detailed description of both the numerical resolution and the analysis of the
internal flow structure under a solitary wave. The numerical code used in this
study is provided in open source for those interested readers.
