Enabling the Use FDM Jacobian option in the Analysis settings can improve convergence by using a more accurate Jacobian.

If the cable body has an initial curvature, the simulation will include the bending effects, and the cable will try to return to a straight shape due to restoring forces. When the cable has high bending stiffness or the curvature is large, these forces can cause high accelerations at the beginning of the analysis, leading to a reduced step size. To avoid this, you should run a preliminary analysis that sets up the initial configuration before starting the main simulation.

In cable winding analysis, as the number of windings increases and the contact area expands, the corresponding increase in stiffness should be properly captured. To ensure accurate results, set the Stiffness Type to Considering Contact Area in the Contact Properties.

To properly mesh the cable, add Mesh Sizing and scope the edge on the cable. Then, set the Element size or the Number of divisions to the desired value. Set the Behavior to Hard and the Bias type to No Bias.

This error occurs when a node in the cable body is assigned to more than two elements, which violates the requirement that each node can belong to a maximum of two elements in a cable body. To resolve this issue, verify that the cable body is modeled as a single, independent line body. If the error persists, clear the generated mesh data and reattempt the meshing process.

Because the solver accounts for the deformed shape of the beam elements, significant bending may cause discrepancies between the contact point location shown in the Vector Display of the Standalone Postprocessor and the actual geometry location.
