Hello, <\/p>\n

I am doing a simulation on a bulk carrier using AQWA (Hydrodynamic diffraction module) to map the loads in Mechanical. However, when I insert the Hydrodynamic pressure tool and set the frequency corresponding to the ship’s length, I get an acceleration (gravity) acting on the center of gravity in the positive Z direction (upwards). If I don’t include the hydrostatic pressure loads I don’t seem to get this acceleration. My goal is to ultimately have a representation of the hogging and sagging loading conditions on the ship, but currently the acceleration makes it that my structure is moving upwards. Also when I turn off the Perform mass\/inertia check I still get the same acceleration. Is there a way to include the hydrostatic pressure and disregard the acceleration caused so that I could represent both load cases mentioned above?<\/p>\n

Appreciate your help and support.\"\"<\/a><\/p>\n","protected":false},"template":"","class_list":["post-286962","topic","type-topic","status-closed","hentry","topic-tag-aqwa"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["286401","183765"],"_bbp_author_ip":["23.217.200.46"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1285"],"_edit_lock":["1686037795:62321"],"_bbp_status":["publish"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["286962"],"_bbp_forum_id":["27791"],"_bbp_engagement":["183765","286401"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["287654"],"_bbp_last_active_id":["287654"],"_bbp_last_active_time":["2023-06-08 07:12:02"]},"test":"saif187ehotmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/286962","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/286962\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=286962"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
