# Physical Validation Experiment
## Definition
Controlled physical measurement tests model behavior and prediction. PECOS's torch experiments supply the article's specific experiment–simulation interface.
## Regional role
Nuclear-stockpile requirements supplied a consequential setting for predictive computation. Verification addresses the implementation, validation compares the model with physical evidence, and uncertainty analysis qualifies the decision. The university research lineage connects national laboratories, UT methods, TACC computation, and experiments without treating a successful method in one domain as automatic validation in another.
