For analyses that include thermal loads, it is important to have an appropriately defined coefficient of thermal expansion (CTE) and reference temperature for every material and rigid element. This API checks all materials and rigid elements for CTEs and reference temperatures of 0 (default) and creates groups for the user to examine. The message window will note the total number of materials and elements identified, and the data table will show if materials were flagged for their CTE, reference temperature, or both.
