Get an introduction to 3D cable modeling in COMSOL Multiphysics^®. This presentation is the second video in a 3-part series on modeling cable systems. In Part 1, we covered 2D cable modeling in COMSOL Multiphysics^® and discuss topics like capacitive, inductive, and thermal analyses; armor and phase twist; and various bonding types. Here, we cover 3D modeling using a submarine cable model as an example.

Discussion topics include:

Building geometries of double helically twisted cables
Building meshes for large 3D periodic structures
Analyzing twisted periodicity
Investigating inductive effects in 3D
Comparing 3D results with those from 2D and 2.5D models
