Abstract:

The computer program HYDRO, a hydrostatics program using cubic parametric splines for curve fitting, is presented. Program documentation and the instructions on program usage are included. Previously at DTNSRDC, a complete hydrostatic analysis of a given hull form required the execution of three separate computer programs. In an effort to consolidate and improve these programs, a new computer program, HYDRO, was written. Because the number of programs has been reduced to one, the time required to complete the analysis has been shortened. The original programs used the trapazoidal rule for calculating the sectional areas and volumes. HYDRO uses parametric splines to define the hull shape to allow exact integration, which improves the accuracy of the results.
