H-Frame Dipole

The Opera Static Electromagnetics Module computes magnetostatic and electrostatic fields or DC current flow in three dimensions. It uses the FE method to solve Maxwell’s equations for the static case in a discretized model. For magnetostatics, the algorithms used in the Static Module automatically treat volumes in the model which contain magnetic sources differently to volumes without sources.

It is a powerful method that avoids cancellation errors that may occur using alternative solution methods. As a result, the accuracy of the solution is often far higher than would be expected from an FE analysis and this is proved by many years of comparison with measured results. The Static Module solver has been used extensively in scientific and engineering applications.
Magnetic material properties can be specified as linear, non-linear, isotropic, anisotropic, laminated or permanent magnet. Coils/solenoids are represented using a proprietary method which uses the Biot-Savart integral to calculate magnetic fields from coils with extreme accuracy. Opera-3d includes a library for easy definition of standard shapes, such as solenoids and racetracks, but coils of any topology can also be created.

The program uses an iterative solution technique to calculate the potential at each node of the mesh. This method is memory-efficient and computationally fast.

Opera is a multi-physics software suite which allows coupled simulations to be performed. 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.
