Hybridization of 3D PEEC and MTL Solutions for Bidirectional Cables Simulation in 3D Environment

New Hybrid MTL/3D PEEC approach allows to take into account bidirectional cable harness interaction with 3D environment.

In this solution, cable bundles are modeled using 2D LCTL approach, while 3D interaction of cables with all other objects is modeled using 3D PEEC approach. As a result, combined equivalent circuit of the model is constructed, which can be calculated using different SPICE-like solvers. User can calculate voltages, currents or S-matrix parameters using equivalent circuit or even calculate currents and charges 3D distribution on the model and radiated electric and magnetic fields.

The connection between cables and 3D environment is established with extended connectors with two or several terminations based on cable termination nodes and 3D PEEC pins.
