Post-processing (Uncertainty Assessment)

Simulation error: the difference between a simulation result S and the truth T (objective reality), assumed composed of additive modeling δSM and numerical δSN errors:

Verification: process for assessing simulation numerical uncertainties USN and, when conditions permit, estimating the sign and magnitude Delta δ*SN of the simulation numerical error itself and the uncertainties in that error estimate UScN

Validation: process for assessing simulation modeling uncertainty USM by using benchmark experimental data and, when conditions permit, estimating the sign and magnitude of the modeling error δSM itself.

Validation achieved
