A new method is presented for simulating the eddy currents induced in magnet cryostat structures by switching gradient coils. Multiple thick cryostat layers are modelled accurately using the network method. Fourier decomposed basis-functions in z and Φ allow the 3D simulation of eddy currents from X, Y, Z or any other coils. Simulations are applied to the cryostat of a HTS magnet currently under construction.
