The model is composed of shell elements and beams, with connectivity established using the batch connection feature in ANSYS Mechanical&rsquo;s mesh structure tree.&lt;\/p&gt;&lt;p data-renderer-start-pos=&#8221;410&#8243;&gt;I have successfully obtained stress results and other outputs required for the analysis. However, I have not been able to extract the Bending Moment and Shear Force diagrams at transverse sections along the ship&rsquo;s length.&lt;\/p&gt;&lt;p data-renderer-start-pos=&#8221;624&#8243;&gt;These diagrams are essential as they are needed for subsequent loading adjustments based on the shear forces and bending moments I get from my analysis results.&lt;\/p&gt;&lt;p data-renderer-start-pos=&#8221;624&#8243;&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/10\/30-10-2024-1730285878-SF-BM in whole ship.png\" alt=\"Bending Moment and Shear Force Diagrams\" \/>&lt;\/p&gt;&lt;p data-renderer-start-pos=&#8221;746&#8243;&gt;After researching in many ANSYS forums and in the internet, I found from other FEA program that this is possible. For example, see relevant link:&lt;\/p&gt;&lt;p data-renderer-start-pos=&#8221;908&#8243;&gt;&lt;span aria-expanded=&#8221;false&#8221; aria-haspopup=&#8221;true&#8221; data-testid=&#8221;hover-card-trigger-wrapper&#8221;&gt;<a href=\"https:\/\/tecnodigitalschool.com\/how-to-make-free-body-cuts-in-abaqus\/\">&lt;span class=&#8221;css-1cwva94&#8243; data-testid=&#8221;inline-card-icon-and-title&#8221;&gt;&lt;span class=&#8221;css-1lcr4h8&#8243;&gt;<img decoding=\"async\" src=\"https:\/\/tecnodigitalschool.com\/wp-content\/uploads\/2021\/02\/cropped-salamandra_solo-1-32x32.png\" \/>&lt;\/span&gt;&lt;span class=&#8221;smart-link-title-wrapper css-0&#8243;&gt;How to make free-body cuts of your model in Abaqus &#8211; TecnoDigital School&lt;\/span&gt;&lt;\/span&gt;<\/a>&lt;br&gt;&lt;br&gt;&lt;\/span&gt;I was unable to find a similar feature in the ANSYS. The Shear Forces and Bending Moments must be produced by the stresses \/ nodal forces occured in the model.&lt;\/p&gt;&lt;p data-renderer-start-pos=&#8221;1083&#8243;&gt;Could you advise if there is a way to implement a procedure to obtain these diagrams in ANSYS?&lt;\/p&gt;&lt;p data-renderer-start-pos=&#8221;1182&#8243;&gt;I have attached screenshots showing an example of the bending moment and shear force diagrams I aim to achieve for longitudinal sections of the ship with transverse cross-sections and my ship model in ANSYS. Note that my model is only a three cargo hold mode, thus not all the structure of the ship has been modelled.<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/10\/30-10-2024-1730285818-ship_model_ansys.png\" alt=\"Ship Model in ANSYS Mechanical\" \/>&lt;\/p&gt;&lt;p data-renderer-start-pos=&#8221;1504&#8243;&gt;Thank you.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-391964","topic","type-topic","status-publish","hentry","topic-tag-mechanicalworkbench-1","topic-tag-2021-r1-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["476481","58821"],"_bbp_author_ip":["93.109.218.195"],"_btv_view_count":["1619"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["391964"],"_bbp_forum_id":["27791"],"_bbp_engagement":["58821","476481"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["391995"],"_bbp_last_active_id":["391995"],"_bbp_last_active_time":["2024-10-30 12:31:51"]},"test":"mlefkioumail-ntua-gr"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/391964","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\/391964\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=391964"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
