I defined the acceleration in the 3 axis, but then when I have to define the hydrostatic pressure I also have to define a &#8220;hydrostatic acceleration&#8221;. I believe tha the magnitude and direction of the hydrostatic acceleration is the same as the acceleration of the body, but my question is about the sense. For example, if the acceleration of the body in the x axis is positive, will the hydrostatic acceleration in the x axis also be positive? Also, does this has to do something with the &#8220;free surface location&#8221;? I&#8217;m not sure how to define that either.<\/p>\n","protected":false},"template":"","class_list":["post-291645","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["260204","88"],"_bbp_author_ip":["23.217.200.46"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1081"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["291645"],"_bbp_forum_id":["27791"],"_bbp_engagement":["88","260204"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["291895"],"_bbp_last_active_id":["291895"],"_bbp_last_active_time":["2023-07-06 13:17:28"]},"test":"josejbustamanteudec-cl"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/291645","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\/291645\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=291645"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
