We are using the connection machine to perform three-dimensional micromagnetic simulations of films with interesting topological structures such as vertical Bloch lines. A critical element of the computations is the calculation of the demagnetizing field. We have extended the Fourier method of Mansuripur and Giles to three-dimensional films and implemented it on the connection machine. We discuss the algorithm and its parallel implementation.
