This model can calculate HTS stack/coil with various applied current and magnetic field. Its greatest advantage is the calculating speed could be very fast. The model is calculated by integration method, which was first proposed by Brandt for HTS tape. Here it is extended to ReBCO stack/coil calculation. Since the current density is used as the variable, we would like to call it J model.<https://www.htsmodelling.com/?wpdmpro=j_model>
