Opera Solutions for Low-Frequency Electromagnetics

Opera Simulation Software is a Finite Element Analysis software suite which allows users to perform simulations of electromagnetic (EM) and electromechanical systems in two and three dimensions. Opera complements the existing SIMULIA EM portfolio with its strength in low frequency simulation, which is useful for the design of magnets, electric motors and other electrical machines.

Static Module

Used extensively in scientific and engineering applications, the Opera Static Module computes magnetostatic and electrostatic fields. It uses the FEA method to solve Maxwell’s equations for the static case in a discretized model. For 3D magnetostatics, the algorithms used in the Static Module automatically treat volumes in the model which contain magnetic sources differently to volumes without sources. By using this powerful method, the module successfully avoids cancellation errors that can occur using alternative solution methods. Therefore, the accuracy of the solution is often far higher than expected from a Finite Element Analysis. In this module users can specify magnetic material properties as linear, non-linear, isotropic, anisotropic, laminated or permanent magnet. In 3D, users are able to simulate coils/solenoids with extreme accuracy using. The proprietary method in Opera 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.
