This report presents the multiphysical simulation results for the several possible geometries of magnetic levitation systems (MLS) based on second generation GdBa2Cu3O7-x HTS tapes stacks. The geometry of each MLS is based on HTS tapes stacks (whole or split) with the several possible cuts and packing. Each stack is placed in a gradient field of a magnetic assembly of the Ne-Fe-B permanent magnets. The MLS calculations were carried out by the finite element method using the Comsol Multiphysics software and includes a electrophysical and thermal processes complex calculation for FC and ZFC magnetization modes and for cryocoolers (for several possible temperatures) and liquid nitrogen cooling modes. The obtained results showed that splitting of part of tapes in the stack may leads to increasing levitation force. The calculated results are compared with experimental data.
