SWATHGEN Computer-Aided Design System User's Manual.

Abstract

SWATHGEN is an interactive computer-aided design program for SWATH ships, written in FORTRAN 77 on a VAX 11/780. It uses TEMPLATE graphics software for plotting. This program produces faired hull forms, including fairing of the strut-lower hull intersection. SWATHGEN interfaces with a resistance calculation program, REPOW, and a wave resistance optimization program, OPTVOL, which contours the lower hull to minimize wave resistance. Swathgen produces a complete mathematical description of the hull surface geometry using parametric cubic splines. This description is used to produce plots (Stations, Waterlines and 3-D Views), to calculate hydrostatic properties and to generate a source panel distribution for wave resistance calculations.
