The update includes several new features and general improvements to the electromagnetic field simulation software. These include additional support for multi-core processors and modeling nonlinear surface impedances.
MagNet v7 introduced new parallel computing 3D solvers which are optimized to take advantage of multi-core processors. For computational intensive design problems, the simulation time is reduced due to better management of the cores. The new release expands on the software’s support for multi-core processing:
• Parallel computing 2D solvers (static, AC, transient and transient fields with moving components)
• Automatic Meshing and Re-meshing in 2D
• Running concurrent sessions of MagNet solvers in 2D or 3D
You can control the number of cores dedicated to a particular 2D or 3D solve, increasing the number for more computational demanding problems, or distribute the multi-core processing to run several concurrent sessions of MagNet. For larger core machines, several concurrent sessions of multicore solves can be taking place.
MagNet v7.1 lets you simulate the magnetization process; specifically the magnetic field strength inside the permanent magnet component will be determined 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 that it has reached during the magnetization process.
To demonstrate the potential of this new feature, a detailed example on simulating a Halbach cylinder for use in a BLDC servo motor has been published on the company’s web site and can be viewed at http://www.infolytica.com/en/applications/ex0176/ .
General Improvements include:
• Modeling Nonlinear Surface Impedance: the effects of nonlinear BH properties are accounted for when computing surface impedances
• Faster core loss calculations
• New Magnequench NdFeB magnets and other refinements to materials database
