Simulation governance is a term coined by Professor Barna Szabo in a an article written for Digital Engineering in 2015 - A Case for Simulation Governance. The following figure illustrates the supports of good engineering design and how verification and validation are essential. Once verification and validation have been achieved then it is possible to use numerical simulation to model physical reality.
Verification is the process whereby numerical simulation, e.g., finite element analysis, is matched to the underlying mathematical model.
Validation is the process whereby physical experiments are matched to the underlying mathematical model.
Benchmark problems provide theoretical solutions to a problem of interest so that software verification can be undertaken. In some cases, where theoretical solutions are not available, numerical solutions of sound provenance are adopted.
