Material indexing convention

Description

Currently seven predefined materials exist in libamtrack. They are referred to using sequential positive integer numbers (see details). The material definition follows largely the pstar and astar definitions of NIST (http://physics.nist.gov/cgi-bin/Star/compos.pl?ap). material.no = 0 points in contrast to a material defined by the user during run-time. This feature is still under development and not available yet.

Details

The predefined materials in libamtrack are:

material.no material
1 Water, Liquid
2 Aluminum Oxide (Al2O3)
3 Aluminum
4 PMMA (Polymethylmethacrylate, Perspex, Plexiglass, [C5H8O2]n)
5 Alanine
6 Lithium Fluoride (LiF)
7 Air (dry, at sea level)
8 Silicon
9 Copper

You can use AT.material.name.from.material.no and AT.material.no.from.material.name to convert material names into material indices and vice versa. AT.get.materials.data will return all available data for a predefined material.
