Finding inductance is one of the main applications of our magnetic field codes PerMag (2D) and Magnum (3D). In this note I’ll discuss how to use the static-field codes to determine inductance at low and high frequency. I’ll concentrate on the inductance between two wires. A future post will cover the energy method for high-accuracy calculations [...]

As we move forward with Aether (our 3D electromagnetic program), we are simultaneously improving the 2D codes EMP and WaveSim. There are two reasons: 1) we are creating benchmark examples of increasing complexity to test the new code and 2) the 2D programs will be combined with Aether in the new Advanced Electromagnetic Design Suite. This [...] Aether, a comprehensive suite for electromagnetic field simulations, will complete the AMaze series. The program will also be the final large development project in the Field Precision product line. Subsequently, we will concentrate on improving existing programs and expanding customer support. Aether is scheduled for release at the end of the summer. Before describing Aether, I want [...] The MetaMesh manual gives a complete explanation of the mesh generation process, but useful pieces of information may get lost because of the shear size of the document. In this post I’ll review common sources of errors that account for most of the MetaMesh techhelp inquiries. The first two are simple while the third is more [...] Thin sheets are the bête noire of finite-element calculations. Large disparities in scale lead to bad meshes and bad answers. The issue often arises in magnetic-shielding calculations where thin layers of iron or mu-metal are used to reduce the field level around sensitive instruments like photomultipliers. In such cases, it is useful to employ scaling principles [...] |
