Seize the disk!

Introduction

Technical programs can generate a lot of data. File organization is critical if you have multiple simulation projects. I have recently received inquiries from customers who have had problems finding input and output files for our programs. In this note, I will give some general recommendations for disk management and also some pointers on how to [...]

Help help

In this article I will say a few words about our program help system: why it is set up the way it is and how to use it effectively. To get online help in any program, go to the Help menu and click on Manual. The program manual is displayed in your default PDF viewer.

Iron in magnetic-field calculations (1)

Modeling non-linear magnetic materials may be intimidating to new users of PerMag and Magnum. This is the first of a series of articles where I will try to remove some of the mysteries.

To begin, we need a few definitions. I use the quantity B0 to represent the applied magnetic flux density at a point in [...]

Using the ConTEXT text editor

A good text editor is one of the most useful tools you can install on your computer, particularly if you do a lot of technical work. If you are using a primitive utility like NotePad, you owe it to yourself to move up. The good news is that you can get a superb editor for free. [...]

FTabTool update

The OmniTrak code for charged particle dynamics can import information on electric and magnetic fields directly from solutions created by our codes HiPhi and Magnum or from field maps. A field map is a text file with a simple and well-documented format that gives values of (Ex,Ey,Ez) or (Bx,By,Bz) on a uniform Cartesian mesh. The field [...]
