’Simulation of coupled electromagnetic/thermal systems using CAE software’
Electromagnetic induction heating occurs in electrically conducting materials when they are in the presence of time varying magnetic fields. This phenomenon is utilised in a wide range of industrial applications. Simulating induction heating effects using computer-aided engineering software requires the solution of both electromagnetic and thermal field distributions. Often a transient solution is required to determine the temperature distribution as a function of time, and this can be complicated by the characteristic wide disparity between the time constants of the electrical and thermal systems. This paper illustrates examples of coupled electromagnetic/thermal field simulations for both steady-state and transient conditions.

Advances in numerical solutions of both ordinary and partial differential equations have led to the development of computer-aided engineering (CAE) software packages that permit the simulation of more complex systems that include real-world deviations that inevitably occur. As the accuracy of simulation results is fundamental for the selection of beam analysis software, this paper from Integrated Engineering Software uses that criterion to examine the most popular numerical methods ...
This paper from Integrated Engineering Software provides guidelines to aid in the proper selection and application of electromagnetic CAE software for simulating and optimising sensor systems. Example electric, magnetic and eddy current simulations will be used for illustration. In particular, this paper will discuss the approximations and simplifications that are often required to produce practical engineering models.
