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 applications. There’s still a lot to discover – **EStat**, **PerMag**, **HiPhi** and **Magnum** have a wealth of capabilities that I couldn’t cover in a short introduction. This article lists resources supplied with the programs or available on our Internet site to help you build your expertise.

First, let’s review materials included with the software packages. There are individual PDF manuals for **Mesh**, **EStat**, **PerMag**, **MetaMesh**, **HiPhi** and **Magnum**. They serve as versatile references through the intensive use of hyperlinks. The active table of contents is displayed if you activate the bookmark view in your PDF reader. Each manual also has a index with active page links.

All software packages include an example library containing ready-to-run, annotated input files for wide variety of applications. Be sure to look at text files in the example directories with names like *HIPHI_EXAMPLE_INDEX.TXT*. They contain a list of the examples along with a brief description of interesting features.

The following free resources are available on our Internet site:

**Finite-element Methods for Electromagnetics**

This full length text was published in 1997 by CRC Press. It reviews the physics of electrostatics and magnetostatics and gives a detailed description of the mechanics of **EStat** and **PerMag**. The book is an essential reference if you want to check under the hood to see how finite-element programs work.

**Example input files**

Complete input files for all the examples discussed in the course.

**Field Precision Technical library**

This Internet page has downloadable copies of the latest manuals for all Field Precision programs. In addition, there are many tutorials in PDF format that review solution techniques for electric and magnetic field applications. Here are links to the tutorials:
