JMAG Script Library

Users can operate almost every feature in JMAG through scripts. Although the JMAG website previously restricted access to sample scripts to authenticated users, we would now like to make this library available to everyone.
Most of the sample scripts written in Python are easy to use with some general programming knowledge. In addition, we are also releasing instructional materials that describe various scripting methods alongside usage examples. These materials should give even those new to JMAG confidence to use the scripting tools to easily automate and streamline analyses and design processes. Going forward, we will continue to enhance this library so that everyone can realize more flexible workflows through scripts.
