A core terminology for Simulation Data Management (SDM) that can be used to define meta-data for engineering simulation. NOTE 1 An engineering simulation is carried out using simulation models of a system, product, phenomenon, or process to:  determine whether a design satisfies its technical requirements; or  predict operational behaviour. NOTE 2 Engineering simulation is often carried out for mechanical products such as automobiles or aircraft, and structures such as buildings and bridges. However, engineering simulation is broader and is used to investigate a wide range of processes such as:  simulations of battery charging and other electro-chemical or dynamic molecular processes;  manufacturing of consumer products, including processes such as forming and welding. The following are within the scope:  the terms used to describe an engineering simulation of discrete products and manufacturing processes; the properties, inputs and outputs of the engineering simulation;  the terms used to describe a simulation model, its properties, provenance and actual use;  the terms used to describe the maturity and appropriateness of a simulation model and simulation results for a possible use, including verification, validation and uncertainty quantification;  the terms used to describe the content of an engineering simulation data set, its properties, provenance and actual or possible use;  a mapping of these terms on to existing top level ontologies. The following are outside the scope:  simulations of distributed networks, such as electrical power networks;  simulation of process plants for the validation, optimisation and certification of operating scenarios;  system simulations for operator training.  comprehensive lists of terms that are specific to a single kind of engineering simulation, such as CFD or crack growth;  a format for the representation of meta-data; NOTE 3 Comprehensive lists of terms that are specific to a single kind of engineering simulation and a format for the representation of meta-data can be addressed by companion standards.
