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 iron.

The performance of many types of electrical machine, including brushless dc, synchronous and switched reluctance is routinely examined in OPERA-2d/ST.
