Core Model Performance for Training Simulators

Cycle specific core performance on a training simulator is a significant motivation for a simulator core model upgrade. The accuracy of the numerical method used in the core model is the primary consideration in the evaluation of the core model. The characteristics of an “engineering grade” core model and the benefits of using such a core model are described. A standard benchmark data set is then analyzed with the engineering grade core model SIMULATE-3R. Further, the effects of using more approximate models are quantified.
