An Introduction to Numerical Methods in Superconductors

A summary is given of some of the various numerical methods which have been used to solve the field equations in superconductors. Some comparisons are made between the commonest methods and constitutive equations used. The difficulties in extending methods to three-dimensional situations are discussed. These include not only the numerical problems but also the lack of suitable parameters for describing flux cutting. Other problems which need to be addressed are losses in complete solenoids of pancake coils and the results of many hysteretic cycles.
