Electromagnetic Compatibility Simulations in the Automotive Sector
To perform an electromagnetic (EM) simulation in an automotive scenario, several challenges need to be addressed. Such simulation models have significant differences compared to models used in contemporary structural simulations. Such a difference is the need to consider the conducting paths across the different metallic components. All metallic parts separated by a distance less than a threshold value need to be physically connected. As in most cases the parts are prepared in their mid-surface position, an extra gap between them is automatically created. This gap needs to be removed. All these gaps should be closed with FE elements. However, some elements are electrically isolated, and for this reason they should not be connected.
