Opera-3d Static Electromagnetics Module
Static Module solver
In this module users can specify magnetic material properties as linear, non-linear, isotropic, anisotropic, laminated or permanent magnet. Users are able to simulate coils/solenoids with extreme accuracy using Opera’s proprietary method which deploys the Biot-Savart integral to calculate magnetic fields from coils. Opera-3d includes a helpful library for easy definition of standard shapes, such as solenoids and racetracks, and also offers users the flexibility to create coils of any topology. Using the “lossy dielectric” option, users can simulate electric fields resulting from charging of low-conductivity dielectrics.
The program uses a sophisticated iterative solution technique to calculate the potential at each node of the mesh. This method offers great memory efficiency and high computer speed for users. Memory requirements are typically 5GB per 10 million finite elements. For example Opera-3d has been used to run a static EM calculation with 120 million elements on a computer with 60GB memory.
Opera is a multi-physics software suite which allows users to perform coupled simulations. This includes the ability to couple a Static Module simulation with a thermal simulation or a stress simulation, for example to calculate the stress due to electromagnetic forces.
Modeller and Post Processor
The Modeller allows users to create models, define material properties, set boundary conditions and excitations, create the mesh and launch the calculation. It allows the user to build models from primitive shapes using Boolean operations, or to import geometry from other CAD programs for which a range of I/O filters is available. Material data can be selected from a library of characteristics or input from the user’s own data.
The Opera-3d mesh generator has facilities for creating hexahedral, prism and tetrahedral meshes (the mesh can be a mixtures of types). Meshing is automatic, requiring little or no user setting in many cases. However, it does include facilities to finely control the mesh when required.
Solutions are stored in a database that can be interrogated using the Post Processor.
