Assuming a line body is created under the geometry to represent cable elements, the user can use the following steps to add bending stiffness to the cable elements if required by one’s application: 1.On the CAD level (e.g., SCDM, DM) make a duplicate of the line body 2.Create a new cross-section for beam elements 3.Update Mechanical and then generate the same mesh for both line bodies 4.Merge Nodes of both line bodies User can adjust the beam radius in the new cross-section to modify the bending stiffness of the line body. Make sure to adjust the material density so that the combined mass of both line bodies is equal to the actual mass of the original cable. The archived project is attached to demo the process.<\/p>\n
