The Static Field Analysis Program solves for time invariant
magnetic or electric fields.
The magnetostatic solver is used extensively for the modelling
of large magnets including MRI, NMR and accelerator magnets. Opera
built its reputation for speed and accuracy on the ability to
efficiently compute the magnet central field to a high degree of
accuracy (parts per million).
Non-linear and anisotropic materials are well catered for,
including the ability to include anisotropic magnets and laminated
The performance of many types of electrical machine, including
brushless dc, synchronous and switched reluctance is routinely
examined in Opera-2d/ST.
