Benefits of technology

This technology helps researchers measure how well products behave when exposed to heat or cold during different stages of production without having them undergo actual testing at each stage. It also reduces the amount of time needed for these experiments compared with traditional methods that require multiple steps before reaching their final results.

Problems solved by technology

This patented describes an issue where testing large complicated structures requires expensive and time-consuming thermal simulation techniques due to their complexity. Current solutions involve simulations that are difficult or impossible to perform accurately during actual operation without significant errors caused by environmental factors like humidity.
