Field notes
The page describes a workflow from selecting a model family and setting dimensions to inspecting parameters, results, and animated geometry. It lists finite parameter searches and discrete interference checks, while explicitly noting that these checks have coverage limits. Desktop releases include installers and archives for multiple operating systems, with checksums and release notes linked from the download section.
