Real-Time Electromagnetic Visualisation for Large 3D Accelerated Models

Previous work has shown that real-time electromag-netic models can be used to enable an augmented reality-based visualisation of the magnetic field around a single wire over a ground plane. However, as model complexity is increased, the memory usage and simulation times increase considerably, to the point that it would be impossible to use in a real-time visualisation. In this paper, previous efforts are substantially improved by incorporating the Fast Multipole formulation of the Partial Element Equivalent Circuit method alongside the PRIMA model order reduction algorithm. A significantly larger model with 11156 ODEs has been simulated in real-time for smooth augmented reality visualisations. Experimental measurements are used to validate the accuracy of the simulation models used.
