The length unit in use in the file will be determined, if possible, from the value of $g$ and the knowledge that the unit of time is the second. Similarly, the control surface option is not available for the Newman QTFs. But in this particular file the load RAOs results are present for the diffraction method only, so the Haskind option is disabled and may not be selected in this case. In this example, a choice may be made between the different calculation methods employed by WAMIT for the Newman QTFs and the full QTFs. out file you have selected, as illustrated in the following figure: The requested data page of the import vessel data form allows you to choose between the methods that are available in the. Choice of calculation methodsįor some types of data (load RAOs, Newman QTFs, full QTFs) WAMIT may offer results from various different calculation methods. The data are almost all non-dimensional, the main exceptions to this being acceleration due to gravity $g$, and WAMIT's length scale $L$, used to non-dimensionalise the data. out extension and OrcaFlex can import data from such a file. WAMIT outputs its results to a text file with an.
