This appendix contains all the plots and tables for the simulations involving prescribed 0-DOF motion in waves of Model 5514 scaled to the length 142 m. Each of Figures H-1 through H-1000 contains time-history plots of the results from all codes for a single variable during one period of motion. If the code runner did not supply the data, the data vanish identically, or the data are insufficient for a single period, there is no curve for that code. The lack of data in any figure has been noted immediately below the figure. As necessary, the time that appears on the horizontal axis has been shifted so that the wave height at CG is of the form eta etaa sin omega t for some amplitude etaa and some frequency omega. Furthermore, the time t has been replaced by t mod Te where Te is the period of the motion. Tables H-1 through H-2000 contain information related to the results depicted in the figures. Two tables follow each figure. The first table gives estimates of the mean value and the amplitudes and phases of the first and second harmonics obtained by Fourier analysis. The second table gives the minimum and maximum of the variable plotted in the figure. The minimum and maximum of both the filtered and unfiltered variable are provided. Appendix R contains plots and tables for the behavior of the minimum and the maximum of each variable plotted in this appendix versus the wave steepness lambdaH. The headings are the same for both ships and speeds, as are the nondimensional wavelengths and wave steepnesses. The description of the waves is given in tables in the main part of the report. For ease of reference, the tables are reproduced here.
