For software quality assurance purposes, TMAP8 undergoes verification and validation. Verification consists of comparing TMAP8 predictions against analytical solutions in different conditions, which are often simple cases. Validation consists of comparing TMAP8 predictions against experimental data.

Note that in addition to monitoring TMAP8 performance and reproducibility in verification and validation cases, the effects of changes made to TMAP8 are tracked. A series of automated tests are performed via continuous integration using CIVET to help identify any changes in TMAP8's predictions, therefore ensuring stability and robustness. When adding a new verification case, be sure to follow the verification and validation standards.

TMAP8 also contains example cases, which showcase how TMAP8 can be used. Finally, for more references of TMAP8 usage, a list of publications supporting TMAP8 development can be found here.
