Model Calibration and Validation

A model is not useful until we understand just how well it matches reality. Model calibration and validation are two vital steps in developing a useful model.

The match between model and reality will never be perfect, and it does not need to be for the model to be useful – the allowable discrepancy depends on your objectives.

It is possible to have a model that calibrates well for a particular test case, and then produces unphysical results for other cases. The causes for this can be errors in the founding equations, errors in implementation, or omission of important physics. Validation is about confirming the ability of the model to give you a reliable picture of the behaviour of the process or system under scenarios for which you have no test data, and usually involves rigorous testing of the model in parts and as a whole.
