Comparative shopping

Most potential customers want to know how Field Precision 3D software for magnetic fields compares to competing products from Infolytica, Ansys, EM Works,…. I give them what I hope are straightforward answers because an accurate representation of the program capabilities is the best long-term strategy. This post summarizes some of the comparison issues:

How does Magnum compare [...]

Problem STL files

In building three-dimensional finite-element solutions, the eternal hope is the faultless transfer of geometric information from CAD programs. In this scenario, mesh generation is a leisurely activity, simply a matter of clicking a few commands. Unfortunately, reality often intrudes. We live in a world where people can’t even make a universal phone charger, let alone a [...]

Example library improvements

Learning technical programs can be difficult. There are many details to enter correctly and many potential pitfalls. My belief is that working examples are best way to help new users get a quick start. Over the years, the growth of our example libraries has been a bit haphazard. New examples reflecting current consulting projects could overlap [...]

Fields and Q factor for a high-power, annular beam klystron

The reason there has been a long interval since my last post is that I have been working intensively on Aether, our new 3D electromagnetic code. The program is performing beautifully in tests and is well on schedule for the September 30 release.

In this post, I want to complete an example started in a previous one [...]
