<p>Hello,<br><br>Recently I am trying to implement a FEA according to Common Structural Rules (CSR) for Strength Assesment for a Bulk Carrier, using ANSYS 2024R2<\/strong>.<br><br>Currently, the geometry was created in Rhinoceros<\/strong> and was transferred then to ANSYS Spaceclaim<\/strong>. In Spaceclaim, the geometry in consisted of Shell & Beam<\/strong> elements for 3-dimensions, where the geometry model was succesfully created. The model can be seen below, which was opened in the ANSYS Workbench<\/strong> as Static Strucural Analsysis component and using ANSYS Mechanical<\/strong>:<\/p><p><br><br>The Geometry then was opened in ANSYS Mechanical to implement the Meshing, the Loadings and the Boundary Conditions (BC) of the model.<br><br>1. For Meshing, the command Batch Connections<\/strong> was used to create the connectivity between the Shell & Beam elements of the structure. The mesh succesfully created.<br>2. For the Loadings, a Mapping was created through Python for the Dynamic Load Cases<\/strong> and Loading Condition<\/strong> I would examine with (X, Y, Z, Pressure) for each selected compartment \/ surface. These were brought in by the component of ANSYS Workbench External Data<\/strong>, which some CSV files were imported with the (X, Y, Z, Pressure). The Loadings were succesfully applied also.<br><br>The issue seems to be with the Boundary Conditions<\/strong>. The CSR prescribe that the Boundary Conditions should be applied as follows:<br><br>\"upload_2024-11-1_9-31-46.png\"<\/p><p>The points are given in the below image:<\/p><p><br><\/p><p><br>For the Cross Sections, Beams with the mechanical properties described in [2.5.4] were built, for both Aft & Fore End.<br><br>Currently I am struggling to apply the Boundary Conditions. I tried the Remote Displacement<\/strong> (by using Rigid behaviour) for each Independent point<\/strong>, but the analysis gives me warnings that there might be a rigid body displacement. Also the Intersection of centerline and the inner point displacement fixing was created. <\/p><p>What I would like to achieve is the following connection:<\/p><p><\/p><p><br>My question is, how I apply properly the above Boundary Conditions<\/strong>, though ANSYS’ environment? Do I need to insert a Remote Point<\/strong>, use Remote Displacement<\/strong> or something different than these?<br><br>Thank you.<\/p><\/p>\n","protected":false},"template":"","class_list":["post-392385","topic","type-topic","status-publish","hentry","topic-tag-ansys-mechanical","topic-tag-boundary-conditions","topic-tag-link-2","topic-tag-remote-displacement","topic-tag-remote-point","topic-tag-rigid-2","topic-tag-ship"],"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
