To accompany the development of High Temperature Superconductor (HTS) magnets at the Laboratoire National des Champs Magnétiques Intenses, we have initiated an activity on implementing numerical models to simulate HTS with the Feel++ finite element (FE) library used for the simulation of the lab high field resistive magnets. In this work, we give an overview of the status of the implementations. We focus on the modeling of the Nougat HTS – that reached 32.5 Tesla in a resistive magnet background field of 20 Tesla. Simulations based on the A and T-A formulations are presented.
