Abstract: A method for assessing validation points for a simulation model. The method includes: obtaining a reference measured value for at least two measuring points; determining a model form error for each of the at least two measuring points, based on a deviation between the reference measured value of the particular measuring point and a probability distribution for a simulation value at the measuring point, the probability distribution being obtained from the simulation model; forming a metamodel of the model form errors, based on the determined model form errors for the measuring points; determining an uncertainty of the metamodel for at least one further data point that is not contained in the measuring points; and defining the at least one data point as sufficient for a virtual validation if the uncertainty of the metamodel at the at least one further data point is less than a predefined limiting value.
