Expanded plot features in MagWinder

One of the major task in simulating three-dimensional electromagnets is the definition of complex drive coils. The utility MagWinder is part of the Magnum program suite. Drive circuits are represented in Magnum by dividing them into a large set of short segments (or current elements). MagWinder provides an interactive environment where users can build magnet windings [...]

New CAD editor compatible with Mesh

Mesh is our automatic generator for 2D meshes of conformal triangular elements. The program includes a convenient Drawing Editor to define boundaries of regions (physical objects) in the solution volume. This mini-CAD utility is easy to use and has many useful features. Nonetheless we included the option to import data from popular CAD programs for two [...]

Emittance of a circular beam

Emittance characterizes the degree of disorder in a charged particle beam. The transverse emittance parametrizes the thermal spread of transverse momentum. Random motion results in an effective pressure that determines focusing forces necessary to confine a beam as well as the minimum spot size of a focused beam. My text Charged Particle Beams (available for download [...]

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 [...]
