Evaluating Surface Hydrostatics

A limited range of hydrostatic particulars may be evaluated from the surface. Selecting DISPLAY \ HYDROSTATICS or launches the Calculate Hydrostatics dialog (Figure 3:125 below), into which the user enters the draft and trim values to use. If the surface is modelling a moulded form, the user can specify a shell thickness value (greater than zero) to be added. Selecting Calculate causes the hydrostatics to be displayed in the output window (Figure 3:126 below).

Figure 3:126. Hydrostatics evaluated from the surface are displayed in the output window.

Note that the values of the overall dimensions used in the calculation of the form coefficients (CB, CP, CWP ) are taken from the general particulars that have been specified for the design - they are not evaluated from the current surface geometry. The hydrostatics are evaluated using the current project faceting settings, which determines the accuracy of the results.
