The model uses a homogenization technique to calculate the current distribution inside the superconducting layers of a HTS stack where each tape carries the same net current as it would be the case in a coil. The model estimates the AC losses of the stack. The homogenized model runs significantly faster than a reference model including the geometry of all the tapes in the stack.
