This page can be used to request a demo version of SIMION.
Limitations: The demo has limitations in saving and refining your own geometries, and is mostly useful for exploring the user interface and trying out a few of the existing examples (not for creating your own geometries). It has some tutorials but lacks a manual. Therefore, it is not fully functional. We recommend taking a look at the "helpful starting points" below for background information on SIMION.
