Consistent accuracy and precision

For nearly 30 years the Opera finite element (FE) software for electromagnetic design has been used by scientists and engineers for designing and optimizing magnet systems to achieve the most demanding levels of performance. Opera has earned its position as the foremost FE design tool for magnets of all types by its consistent accuracy, ease of use, and ability to handle large and complex simulations routinely.

The MRI/NMR application is particularly demanding because extremely high field precision is required in the imaging zone. Opera was developed from the outset with this requirement in mind, and as a result most of the leading MRI and NMR equipment manufacturers use Opera for designing superconducting magnets, for carrying out quench simulations, and for designing magnet shielding. The software has evolved over the years and today provides comprehensive multi-physics simulation that is capable of investigating thermal and stress in addition to electromagnetics.

Find out how Opera helped Cryogenic, one of the world’s leading producers of cryogenic equipment

Cryogenic uses its own in-house software to design the basic mechanical layout and coil structures of a magnet, fine tuning its field profile with magnetic material to meet the customer’s specific needs. The shape and placement of the magnetic pieces are critical to the magnet’s performance, and are determined through extensive electromagnetic field simulation. Following the initial design phase, the company employs Opera’s 3D Modeller to create a very detailed geometric model of the proposed design, from which is generated a mesh of finite elements for numerical solution using the static electromagnetic field simulator.
