The Opera-2d course begins by providing a short introduction to the workings of the Pre and Post-Processor and describes the type of problems that can be analyzed using the Opera-2d solvers. Aspects of Finite Element Modeling including boundary condition assignment, discretization and mesh adaption are also discussed.
Step by step examples on Electrostatic and Magnetostatic problems are used to get users familiarized with the software during the first day. The popular subject of Material Properties (non-linearity, anisotropy and permanent magnet materials) is discussed before embarking on the solution of transient eddy current problems. An important feature of the course is its focus on applications. The use of the wide variety of Opera-2d solvers to address specific applications is demonstrated by further examples such as:
- A moving coil loudspeaker
- A brushless dc motor (Opera-2d/rm)
- A coaxial line (Opera-2d/ld)
- An induction heater (Opera-2d/ac)
- An electron gun (Opera-2d/sp)
An advanced lecture on parameterization and an introduction to the Command Interpreter and application oriented dialogs is also provided.
Three dimensional modelling brings further insight into any design process. The Opera-3d three day course provides the user with structured guidance in 3D design, including the analysis programs Static Electromagnetics, Dynamic Electromagnetics, Motional, Magnetization (& Hysteresis), High-Frequency, Thermal, Stress, Quench. The overall modeling process (pre-processing, analysis, post-processing) is presented initially using a simple electric field example.
Facilities available at each stage are then studied in depth using magnetostatic/dynamic models. Nonlinearity, permanent magnets, periodic structures, accuracy, eddy currents, velocity effects and motion are all covered along with the wide range of facilities for extracting results. Contour plots, graphs and maps of fields and potentials, force and torque production, power dissipation and charged particle tracking illustrate the range of results available, including derivation of important design parameters such as inductance.
Theoretical aspects are covered in sufficient depth to allow accurate use of the programs for the users own designs, while “hands on” example models illustrate the rich variety of model creation tools and their efficient use.
