“…In a global Cartesian coordinates (x, y, z), the field quantities to be solved are expanded by a set of basis functions, used to interpolate field values from nodal values [11]. Since the basis functions are associated with each element individually, it is convenient to write them in the local coordinates (u, v, w), which are independent of the shape of the element.…”

“…It is important to note that frequency domain is desired in this (and most) EMC analysis since the output under investigation is electric field as a function of frequency. Frequency domain numerical techniques such as finite element method (FEM) and the finite element boundary integral (FEBI) was also used for this purpose, resulting in faster simulations in the order of just a few minutes [9][10][11][12]. In this work both FEM and FEBI are used considering a convergence criteria of 0.1 V/m, meaning that the software automatically adapts the numerical discretization (mesh) until the difference on the result between meshes are less than 0.1 V/m.…”

This paper highlights the effects of specific parts of a vehicle in a radiated immunity numerical simulation. The benefits of numerical simulations for electromagnetic compatibility analysis is well known and reported in the literature, nevertheless, the accuracy of the results relies on the mathematical models that is being used on the simulations. Several simulations are addressed in this work, showing how specific parts of a vehicle can affect the electric field inside a vehicle. The commercial package ANSYS HFSS TM was used due to the extremely fast and accurate simulations since it relies on the finite element method technique including hybridizations with the method of moments. This allows complete simulations to be run in under a few minutes with controlled convergence, allowing a more extensive investigation. The simulation results are compared with experimental data obtained from real tests performed at Instituto Nacional de Pesquisas Espaciais showing a good agreement. Keywords-Automotive electromagnetic compatibility (EMC), electromagnetic interference (EMI), finite element method (FEM), method of moments (MoM).
