3-D homogeneous model to estimate AC losses in coated conductor stacks and coils

This model was shared by V. Zermeno, Karlsruhe Institute of Technology.

This model uses a homogenization technique to calculate the current distribution inside the superconducting layers of a racetrack coil and to estimate its AC losses.

The figure shows the normalized current density J/J_c(B) for a quarter of the coil geometry. The sign is used to indicate the direction of the current.
