Using MeshLab with Geometer and MetaMesh

Several years ago, we faced a decision on how to import information from CAD programs into MetaMesh, our 3D mesh generator. There was a sense of urgency for two reasons: 1) we had a consulting project with shaped electrodes that were beyond the capabilities of the native solid models of MetaMesh and 2) users increasingly expected […]

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 μr […]

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 […]
