Simulation électromagnétique à l'aide de 3DEXPERIENCE Simulia

Article by TriMech Solutions, LLC updated February 20, 2023


In our smart connected world, we are rapidly adopting products that are stacked with sensors, antennas and similar devices for communication, data acquisition or monitoring. With Artificial Intelligence-based technologies and a high level of automation that is dominating our daily lives, we are relying on electromagnetic components more than ever. The demand for constant connectivity in our IoT world has increased our reliance on electromagnetic components and expanded the complexity of electromagnetic devices/systems in emerging and long-established industries.

Emerging electromagnetic markets include medical equipment, renewable energy, metamaterials (wearables, optics), unmanned vehicles and electric vehicles [1].  With IoT, use of 5G and Bluetooth is becoming common in industries such as automotive, heavy machinery or transportation sectors. These products need to comply with EMC (electromagnetic compatibility) standards and medical equipment, wearables need to also comply with BioEM standards.

This means it is important to virtually test, i.e. conduct electromagnetic simulation, concurrent to the design process to make the invisible (such as magnetic field, properties) visible and identify issues early on in the design process. Electromagnetic systems often pose multiscale challenges such as wide frequency range and capture of fine details within large electrical structures.

Electromagnetics simulation tools enable the simulation of electromagnetic wave propagation and signal strength related to design and position of devices for communication and detection [1].

Right from product ideation to its design and synthesis of components to meet the required specifications leading up to analyzing electromagnetic performance, electromagnetic simulation software is a true game changer.

Simulia Electromagnetics engineer (EMG-OC) role on the 3DEXPERIENCE platform is powered by industry-proven CST Studio Suite technology.  It enables users to perform wide range of electromagnetic simulations from low frequency, static to high frequency such as optical applications. Capabilities include optimization of antenna and microwave components, electro-mechanical devices, electrical motors, batteries, accurate thermal modeling of PCBs, component layouts and much more.

Electromagnetics Engineer role offers powerful simulation methods such as the unique finite integration technique (FIT), classical finite element method (FEM), the transmission line matrix method (TLM), and hybrid simulation methods. It has specialized solvers for applications such as motors, printed circuit boards, cable harnesses and filters.

With a wide range of complex material models and a fully parametric design environment, it can also perform coupled simulations, for example system-level, multi-physics, field/circuit co-simulation.  Built-in optimizers linked to design model allows users to run what if scenarios and investigate results using the powerful postprocessing – visualization tools, even on a web-browser with 3Dplay app.

Depending upon the solver type used, it offers option for high-performance computing on workstations and on clusters. This lets users opt for either hardware-based acceleration – CPU multi-threading, GPU computing or software-based acceleration -distributed computing and MPI computing.  MPI computing is suitable for solving large electrical models such as lighting strike simulation on aircraft.

Note that the cloud computing on 3DEXPERIENCE cloud uses SIMULIA SimUnits.

For SOLIDWORKS users, Electromagnetics Engineer role provides tight associativity between the CAD and simulation data by means of a connector. This ensures that the CAD and Simulation data always remain synchronized and any design change in SOLIDWORKS model can be transferred to the simulation model on the 3DEXPERIENCE platform.  It enables data management and reuse of simulation data, unlocking the benefits of cloud collaborative design experience.
