Data Optimization in Thermo‑Calc

More about data optimization and PARROT, including a video about how to use PARROT, is available on the Thermo‑Calc Software website. The video is also available on our YouTube playlist.

The actual performance of the optimization of a system is primarily done in the PARROT module, and in its sub-module ED_EXP. The POLY and POST modules are used to calculate and plot property or phase diagrams based on the optimized variables. This allows you to visually assess how good a fit you have achieved between your calculated results and your experimental data.

The end result of a successful optimization is typically an updated Thermo‑Calc database file (with filename extension *.TDB) or a new database file.
