Dynamic advances in electromagnetics simulation
The latest version of the MagNet 6 electromagnetics simulation package from Infolytica features a full motion-solving capability for translationally symmetric and axisymmetric devices.
Solve thermal problems with dedicated software
ThermNet is designed to solve thermal problems involving conduction, convection, and radiation, and allows 2D problems (XY and RZ) to be described and steady state and transient analyses performed
MultiNet now opens up the possibility of a generalised coupling of solvers between packages.
Previously, two classes of thermal simulation were possible.
First, temperature-dependent magnetic characteristics of materials may be used, in association with MagNet's parameterisation capabilities, using temperature as a parameter.
In this case, single-package operation allows analysis of applications like temperature effects on magnetic lifting magnet capability, torque in permanent-magnet motors, and gap fields in loudspeakers.
The second class of application requires the close coupling of MagNet with the thermal analysis package ThermNet to calculate temperature rise consequent to losses, and resultant reduction in conductivity.
Typical analyses here include eddy current heating allowing for temperature-dependent skin depth, induction heating of a material where the Curie temperature is exceeded locally, busbar heating and case hardening of a bearing raceway.
MultiNet allows the coupling of any of the MagNet solvers with the ThermNet static and transient thermal analysis.
So the coupling of a 3D electromagnetics solver with a 2D thermal solver is possible, as is the coupling of magnetic and thermal transient analysis.
Applications now covered include the induction heating of a hollow square-section conducting tube by an encircling spiral coil, induction heating of a hollow conducting tube by a nonconcentric encircling spiral coil, and demonstration of the effects of temperature on the behaviour of a levitated conducting ring.
