4.2.2. Mesh Cell1. Double-click the Mesh Cell in the Workbench to launch Hydrodynamic Diffraction(AQWA). Note the coordinate system is displayed in the lower right-hand corner.2. Highlight Geometry under the Tree Outline.3. The program will automatically import the surface body from Design Modular asindicated in Imported Preferences under the Details of Geometry, as seen inFigure 4.14.4. Enter Sea Geometry details. In this work the Sea Level is 0 in., Water Depth is 11in. (28 cm), Water Density is 3.7028E-2 lb m /in. 3 (1025 kg/m 3 ), Water Size X is39370 in. (100 m), and Water Size Y is 5.875 in. (15 cm), as seen in Figure 4.14.Figure 4. 14 Details of the Geometry5. Right-mouse click on Geometry in the Tree Outline, which will generate a contextmenu, as seen in Figure 4.15. Select Add >> Point Mass.6. Under Details of Part set Fixity Options to Structure is Fixed in Place. Thus,the program solely solves for the diffraction problem, as seen in Figure 4.15.65
