Resources for finite-element electric/magnetic field solutions

This is the concluding article of the online course, Electric and magnetic field calculations with finite-element methods. In the course, we’ve had a chance to get familiar with the operation sequences and data organization of 2D and 3D programs and discovered many useful analysis techniques. Hopefully, the material will help you get started on your own […]

3D magnetic fields: iron and permanent magnets

This article is part of the continuing online course, Electric and magnetic field calculations with finite-element methods. For the final calculation of the course, we’ll characterize forces in a latching solenoid. The example exercises the full finite-element capabilities of Magnum and provides an opportunity to use the force-calculation capabilities of MagView. In preparation, copy the files […]

3D magnetic fields: free-space calculations

This article is part of the continuing online course, Electric and magnetic field calculations with finite-element methods. We’ll continue the topic of 3D magnetic fields by discussing Magnum operation in the FreeSpace mode. The mode applies to calculations in an infinite space without magnetic materials. In other words, all objects in the solution space have ?r […]

3D magnetic fields: defining coil currents

This article is part of the continuing online course, Electric and magnetic field calculations with finite-element methods. We’ll start the final topic, three-dimensional magnetic field solutions. The previous articles on electrostatics covered many common techniques for 3D solutions, particularly mesh generation. Here, we’ll focus on the differences between Magnum and HiPhi calculations that arise from the […]

3D electrostatic application example: mutual capacitance

This article is part of the continuing online course, Electric and magnetic field calculations with finite-element methods. We’ll conclude the application example by calculating the electric field and discussing two useful techniques:

Determining mutual capacitances in a system with multiple electrodes.
Setting up HiPhi solutions for automatic operation in the background.

Run HiPhi, click Setup and load CapDetector.MDF. We […]
