To do this in Aqwa Workbench, the time domain Analysis Type should be set to &lsquo;Irregular Wave Response&rsquo; or &lsquo;Regular Wave Response&rsquo;, as this directs the Aqwa solver to calculate the hydrostatic pressure under the instantaneous wave surface. Drift loads will not be included, however.&lt;\/p&gt;&lt;p&gt;Right-click on the time domain Hydrodynamic Response Solution, then Insert Result &gt; Structure Forces &gt; Hydrostatic Only. In the result details, change the Component to Global Z. Solve and evaluate this result, then divide the values by rho*g (where rho is water density and g is gravitational acceleration) to get the instantaneous volumetric displacement.&lt;\/p&gt;&lt;p&gt;I hope this helps.&lt;\/p&gt;&lt;p&gt;Mike&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-357756","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/357756","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/357756\/revisions"}],"predecessor-version":[{"id":357757,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/357756\/revisions\/357757"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=357756"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
