If the Hydrodynamic Diffraction analysis contains multiple structures, it is possible to use the direct method to map pressures onto one of those structures in the Static Structural system. The direct method also permits mapping onto the outer surfaces of Solid Bodies. This method avoids the loss of accuracy due to interpolation, but it cannot be used to map loads onto Line Bodies.&lt;\/span&gt;&lt;\/p&gt;&lt;p&gt;&lt;span style=&#8221;font-size: 12pt;&#8221;&gt;Check section 8.1.4.1.4 in the below help documentation for more information.&lt;\/span&gt;&lt;\/p&gt;&lt;p&gt;&lt;span style=&#8221;font-size: 12pt;&#8221;&gt;<a href=\"https:\/\/ansyshelp.ansys.com\/account\/secured?returnurl=\/Views\/Secured\/corp\/v241\/en\/wb_aqwa\/aqwa_extensions_hydro_pressure_import.html\" target=\"_blank\" rel=\"noopener\">Importing Hydrodynamic Diffraction Pressures and Loads to Mechanical<\/a>&lt;\/span&gt;&lt;\/p&gt;&lt;p&gt;&lt;span style=&#8221;font-size: 12pt;&#8221;&gt;For the ACT extension, refer the below manual.&lt;\/span&gt;&lt;\/p&gt;&lt;p&gt;&lt;span style=&#8221;font-size: 12pt;&#8221;&gt;<a href=\"https:\/\/storage.ansys.com\/mbu-assets\/beta\/Mech\/v192\/Aqwa_Hydro\/Aqwa_HD_loadmapping_beta.pdf\">Microsoft Word &#8211; Aqwa_HD_loadmapping_beta.docx (ansys.com)<\/a>&lt;\/span&gt;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-364270","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hi Issac,The meshes in the Static Structural and Hydrodynamic Diffraction systems are generally not coincident, which necessitates some approach to map the hydrodynamic pressures onto the structural mesh.
