Electromagnetism
Design and optimize your electromagnetic systems
Electromagnetism plays a role in many industrial applications such as induction heating, electrical machines, sensors, high-voltage devices, and electromagnetic processes.
By solving Maxwell’s equations, SIMTEC develops numerical models using COMSOL Multiphysics® to accurately predict the behavior of electric and magnetic fields, optimize the performance of your equipment, and reduce the need for experimental testing.
The electromagnetic phenomena studied
SIMTEC is able to model a wide range of electromagnetic phenomena, in 2D or 3D, including:
- spatial and temporal distributions of electric and magnetic fields;
- the distribution of electric potential;
- induced currents and their topology;
- the transmitted power, including the calculation of resistances, capacitances, and inductances;
- induction heating;
- electromagnetic stirring;
- magnetohydrodynamics (MHD);
- crystal growth.
These simulations can be coupled with heat transfer, structural mechanics, or fluid mechanics to accurately represent the interactions between the different physical phenomena.
Optimize your electromagnetic equipment
Electromagnetic simulation makes it possible to improve the performance of many industrial systems while reducing development costs.
Our calculations can be used, in particular, to optimize:
- the design of an inductor;
- induction heating processes;
- the geometry of an electrode furnace;
- electromagnetic stirring of conductive fluids;
- crystal growth processes;
- the performance of complex electromagnetic devices.
They also make it possible to minimize the risk of electrical breakdown in high-voltage equipment, notably through the analysis of creepage distances, electrical insulators, and the distribution of electric fields.
Accurate modeling of coupled phenomena
In many applications, electromagnetic phenomena are strongly coupled with other physics. Induced currents generate Joule heating, electromagnetic forces cause mechanical deformations, while conductive fluid flows are influenced by magnetic fields in magnetohydrodynamics (MHD) applications.
The simulation tools developed by SIMTEC make it possible to simultaneously solve all these phenomena in order to obtain highly accurate results, particularly for:
- the dynamics of induction heating;
- the heat generated by Joule effect;
- the calculation of electromagnetic forces, using an energy-based approach or the Maxwell stress tensor;
- mechanical displacements induced by these forces.
This multiphysics approach ensures an accurate representation of the actual behavior of your products and processes.
Analysis of electromagnetic phenomena makes it possible to optimize the performance of electrical equipment, induction processes, and electrotechnical systems.
