The ElecNet and ThermNet analysis packages can be linked for coupled simulations, thereby expanding the capabilities of the design software.
The latest release of ElecNet and ThermNet software are available. The two finite-element analysis packages can be linked for coupled simulations, expanding the capabilities of the company’s design software. An adiabatic feature in ThermNet can be used for coupled MagNet and ElecNet simulations. The adiabatic feature models sudden and rapid heating, such as the process that takes place when lightning strikes.
The software now offers a seamless and easy coupling that is already available with MagNet and ThermNet. Performing a coupled analysis determines the non-linear steady state temperature distribution due to electric heat sources for static and time-varying thermal simulations. The coupling works with the transient, current flow, and time-harmonic electric field solvers in ElecNet
The combinations of the new features allow for devices such as surge arrestors, cables, transmission lines or other phenomena such as dielectric heating to be accurately simulated. To demonstrate the accuracy and types of results that can be obtained from these new additions, the company has released a detailed example simulating a surge arrestor being struck by lightning.

Recently released MotorSolve v2.5, electric machine design software, has many improvements to the template modeling engine, results charts, and the user interface.
Recently released MotorSolve v2.5, electric machine-design software, has many improvements to the template modeling engine, results charts, and the user interface. A new online documentation resource is also available with the release. Improvements to the template library include a new interior/exterior wound-rotor template. The template-modeling engine used in MotorSolve has been fine tuned, allowing for a more intuitive experience. All changes result in more detailed analyses of machine design.
Coinciding with the release is the launch of LiveDocs for MotorSolve. In addition to the basic and general information available in the MotorSolve Help, the MotorSolve Live Docs provides in-depth information for better control and understanding advanced features, such as the Variation Geometry engine, sizing features, stator windings, and lumped parameters. Specific motor concepts also discussed include general PWM and cogging torque.

Help for generator designers

The first release of V7 introduced multicore solving capabilities, which let users take advantage of dual, quad, and 8-core processors to get faster results from the software. Multicore features will be added in v7.1.
Developer of MagNet says its Version 7, available mid-spring 2010, will let users simulate the magnetization of a permanent magnet, expand on MagNet’s multicore support, and include other new features. V7.1, from Infolytica Corp., will allow simulating and determine the magnetic field strength inside the permanent magnet component by the magnetization pattern and source current in the magnetizing coils.
The result will be a permanent magnet for which each point inside will have a different recoil loop depending on the flux density reached during magnetization.
The permanent magnet can be then used as a component in an electromagnetic device, such as a generator or motor, for which further simulations can be performed as to study the performance based on the magnetized state that was stored from the previous simulation.
It will be available for PC’s running Microsoft Windows XP, Vista, and 7 in Spring 2010
