Simulation and Analysis of Electromagnetic Fields
Electromagnetic Simulation Software
Electromagnetic simulation software enables engineers to investigate the electromagnetic properties of components or whole systems efficiently. Electromagnetic (EM) systems often pose multiscale challenges, such as wide frequency ranges and electrically large structures with fine detail. Dedicated solvers exploit specific numerical technologies for fast and accurate simulation. EM simulation can be applied throughout the entire design process. From the inception of an idea, to the synthesis of components to meet specifications, to analyzing the electromagnetic performance under operational conditions: virtual prototypes are transforming the design cycle.
SIMULIA Electromagnetic Simulation Key Benefits
Faster Design Turnaround Times
Simulation accelerates analysis and optimization, allowing shorter design cycles and providing a competitive advantage.
Reduced Reliance on Testing
Compared to physical testing, simulation is faster, more cost-effective and can be implemented earlier in the design cycle. It can also reveal behavior not visible in a test
Understand Complex Systems
High-performance simulation can model the behavior of large or complex systems, such as antenna performance on a busy street, signal integrity on a high-speed PCB, or safety of a medical device in the human body
Reduced Work through Automation
Automated meshing, optimization and post-processing removes tedious set-up work and lets engineers get the results they need faster
Leverage Design Models
Unified modeling and simulation (MODSIM) means simulation can be performed directly on geometry from CATIA or SOLIDWORKS in a unified design environment, reducing the time needed for model building
Full Analysis with Multiphysics Simulation
Electromagnetic simulation can be supplemented by other disciplines, such as fluids simulation, structures simulation, multibody system simulation and vibro-acoustic simulation
Improve Product Performance and Quality
EM simulation software is a game changer for reducing the time and cost of bringing a product to market. It is widely used not just in the high-tech industries of electronics and communication, but also in aerospace, defense, transportation and life sciences. Analysis with EM software ranges from individual components such as antennas, sensors and chips up to entire devices, including aircraft, smartphones and MRI.
Co-design within the SIMULIA product portfolio integrates EM simulation into industry processes. Unified modeling and simulation (MODSIM) accelerates the process of evaluating the performance, reliability and safety of materials and products. Engineers can investigate trade-offs, mitigate issues and optimize the design before committing to physical prototypes, reducing development risk. Multiphysics design flows on the 3DEXPERIENCE platform drive the development process from the earliest stages. Simulia electromagnetic simulation software is available on the 3DEXPERIENCE platform and standalone.

FAQs About Electromagnetic Simulation
3D electromagnetic simulation describes approaches to solving Maxwell's equations in space and time. Methods based on volume discretization are, for example
- the finite element method (FEM),
- the finite integration technique (FIT),
- the finite difference time domain method (FDTD),
- and the transmission-line matrix method (TLM).
These methods are very general and can be used to simulate all classes of problems. However, there are methods that are far more efficient for specific problem classes, such as the method of moments (MoM), boundary element method (BEM) mode matching and physical optics.
Fullwave em-simulators solve Maxwell's equations without approximations based on a problem's special physical nature. They typically provide solutions to high-frequency electromagnetic applications such as antennas or components. SIMULIA provides time-domain and frequency-domain em-simulators.
The CST Studio Suite transient solver offers solutions based on the finite integration technique (FIT) and the transmission line matrix method (TLM). These solvers are particularly well-suited to calculate broadband results of wideband structure. These em-simulators are very memory efficient and capable of dealing with large, highly complex and highly inhomogeneous problems, their implementation on GPUs and clusters further facilitates this use.
The statics simulation range comprises electrostatics, magnetostatics and stationary current flow. Based on Opera and CST Studio Suite technology em solvers for all three static application cases, The Electrostatic Solver is perfect for simulating static electric fields and is ideal for sensors and touchscreens. The Magnetostatic Solver helps design electrical machines as well as particle accelerator magnets. The Stationary Current Solver is for analyzing DC currents in components with lossy elements, for example, high-power equipment or PCB power distribution networks.
The best electromagnetic simulation software is the one that gets the job done accurately and quickly. One fundamental requirement to accomplish this challenge is the availability of a variety of numerical simulation methods within one software package because not one simulation tool can solve all the simulation challenges. The SIMULIA electromagnetic simulation portfolio offers a wide range of em-simulators for frequency ranges from DC to light.
Numerical simulation of electromagnetic fields is typically based on a discretization of Maxwell's equations in space and time. In the simplest FDTD case, the simulation volume is mapped onto a Cartesian grid. The individual grid cells can be filled with different materials and the electric and magnetic fields are defined along the edges and through the facets of the cells.
