WEMA17: Smart Resolution of 3D Component Intersections in Ansys HFSS Mesh Fusion for Streamlined Electromagnetic Simulation of Complex Electronic Assemblies

Abstract
As operating frequencies rise toward mmWave and sub-THz regimes, electromagnetic interaction between tightly integrated components becomes a dominant factor in system performance. Accurate simulation of complete electronic assemblies—such as connectors on multilayer PCBs with surface-mount components and antennas—is no longer optional; it is essential. Ansys HFSS Mesh Fusion enables full-system electromagnetic simulation using encrypted 3D component models, preserving intellectual property while ensuring accuracy and cross-vendor interoperability. Geometric intersections between components, such as connector pins traversing PCB layers, can disrupt simulation workflows. This presentation introduces intelligent technologies to automatically detect and resolve such intersections within the Mesh Fusion workflow.
