In this paper we present a set of numerical models created with COMSOL Multiphysics. The set includes quantitative models of a superconducting tape operated at 77 Kelvin, carrying a transport current and exposed to external magnetic field; an array of such tapes and a triaxial high temperature superconducting cable. Similar models were created in the past. However, an advantage of our approach is in transparency and traceability for a user, these are provided by using an existing COMSOL example, by applying realistic physical properties to the model tape and finally via step by step validation of the computed results, the models and the input data experimentally, numerically and analytically.
