ESRD's Mission ESRD's primary mission is create and market software tools for the advancement of the quality, reliability and timeliness of information that serves the engineering decision-making process. Motivated by economic incentives, CAE users want to reduce physical testing and increase reliance on numerical simulation. Technical requirement: Predictions based on numerical simulation must be consistently reliable. The conceptual and technological prerequisites are now sufficiently mature for industrial applications. The terms verification and validation are used in formulating the new requirements: Verification refers to a process by which it is ascertained that the errors of approximation are within acceptable limits. Validation refers a process by which it is ascertained that the mathematical model is a reasonable representation of the physical reality it is supposed to represent. ESRD’s software product StressCheck was designed to support V&V tasks.
