Opera Features for Low-Frequency Electromagnetics

Opera provides users with an intuitive graphical user interface (GUI) to create parameterized models or use components or assemblies from a CAD system. The integrated post-processing facilities enable access to the simulation results. Opera facilitates the simulation of machines in dedicated environments. It can consider typical material properties and the influence of other physics domains on the machine performance. Automatic optimization supports design success.

Opera Graphical User Interface

Components or assemblies can be imported from an existing CAD system, or created using the built-in Opera 2D sketcher, or 3D Modeler. The Opera model file contains a complete history of the commands that created it. The user can replay and modify files – using the files as a template to automate the design variations of standard products.

Pre-Processing functionality includes:

  • CAD Import
  • Geometry construction (Boolean operations, Swept faces, Loft between faces, 2d sketching, Copy and transform, Background region, Blend & Chamfer)
  • Parameterization and rebuild
  • Automatic meshing (Mesh control, Layering for skin effect and thin sheets)
  • External circuit definition

After the simulation is complete, the Opera post-processor simplifies the analysis of the results. In addition to displaying the field, temperature or stress, there are numerous functions to prepare and display derived quantities in forms and units familiar to the user. These include forces, power loss and stored energy. In addition, the user can also compute and display particle trajectories through the computed electric and magnetic fields.

Post-Processing functionality includes:

  • Field values:
    • Contours & vectors on 3d geometry surfaces
    • Contours & vectors on arbitrary planar, cylindrical and spherical 2d surfaces
    • Graphs along lines, circles and arcs in 3d space
    • Isosurfaces
    • Export to text files
  • Integrated values (force & torque, energy & power, line, surface and volume integrals, Q-factor)
  • Harmonic analysis
  • Deformed shapes
  • Charged particle tracking (display on geometry, intersection with surfaces, beam current density maps)
