Scientific & Industrial
Specialised techniques are required to model the kinds of equipment used for scientific applications. These can range from mass spectrometers, cyclotrons, magnets (to bend particle beams in accelerators, or for use in a MRI system). Industrial application range from transformers to magnetic heating.
| MRI
In medical MRI systems, highly homogeneous fields must be produced by the magnet system (typically superconducting magnets). To obtain high precision in the modeling, the package Opera-3d/Tosca can be used with its proven record as the most accurate tool for this application.

Magnets Various magnets used in accelerators, and many have been designed using the Opera-2d/st and Opera-3d/Tosca packages with proven accuracy. Material saturation can be included, as well as permanent magnet material and other material anisotropy. |  |
 | RF Cavities RF cavities are in common use in high energy physics applications. The resonance of the complex 3D cavity can be modeled using the Concerto software. |
Heating Eddy current heating is widely used, and both axi-symmetric and fully 3D analysis can be used. The Opera-2d/ac solver can be used to determine the eddy current heat generation, and the Opera-2d/th/thtr modules can compute the temperature rise. In 3D, the Elektra package can be used to model the eddy current heat, and the data exported to other thermal analysis packages. | 
|
 | Transformers For all types of transformer, the Opera-2d/st or Tosca packages can be used to model the non-linear field behaviour. Induced eddy currents can be modelled using Opera-2d/ac/tr and Elektra. |
Shielding Shielding high magnetic fields can be modelled using the Tosca package. The application can include screening of high magnetic field medical equipment (such as MRI). Special techniques allow accurate and efficient computation of these effects. |  |
Low Frequency EMC
Opera has been employed for the computation of electric and magnetic fields from sources such as power lines, substations and railway lines. The effects of electric and magnetic fields from railway tracks on office equipment residing in neighbouring buildings can be quantified. The design of effective shielding is routinely undertaken in Opera.
Cable Junctions and Terminations
The electric field distribution around cable junctions and terminations as well high voltage insulators can be accurately estimated using Opera. Advanced solvers within the Opera suite account for the dielectric and conducting properties of the materials, allowing the designer to specify the dimensions of the insulating materials and the resulting electric field distribution, pinpointing with great accuracy the high stress areas.
