Quasi-3-D Cylindrical Coordinate XFEM Model of HTS Cable

This paper presents a quasi-3-D cylindrical coordinate high-temperature superconducting (HTS) cable model based on the shell element theory. The quasi-3-D meshing elements are used instead of the traditional 3-D meshing elements to overcome the difficulties in meshing. The improved extended finite-element method (XFEM) is proposed to solve the field problem in close-jointed thin layers. The numerical simulation results are reported compared with the experimental test results for the case of an HTS cable with three layers.
