The Material Library contains data for 2500 materials including the elements, minerals, soil, metal alloys, oxides, steels, thermal insulators, semiconductors, and optical materials. You specify a material in the Material Library browser, which enables you to easily find the desired material by name, or UNS (Unified Numbering System) number.

Each material is represented by referenced property functions for as many as 24 key material properties, such as thermal, elastic, or electrical properties, depending on some variable, typically temperature. You can plot and inspect these function definitions, as well as change and add to them. They are then used in any coupling to other physics simulations that also depend on the property function variable in your multiphysics modeling.
