<p> <\/p><p>Hello,<\/p><p>It is possible to calculate the instantaneous displacement of a structure in waves. To do this in Aqwa Workbench, the time domain Analysis Type should be set to ‘Irregular Wave Response’ or ‘Regular Wave Response’, as this directs the Aqwa solver to calculate the hydrostatic pressure under the instantaneous wave surface. Drift loads will not be included, however.<\/p><p>Right-click on the time domain Hydrodynamic Response Solution, then Insert Result > Structure Forces > 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.<\/p><p>I hope this helps.<\/p><p>Mike<\/p><p> <\/p><\/p>\n","protected":false},"template":"","class_list":["post-357756","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
