scalar_calibration_terms


Number of scalar calibration terms

Specification

Alias: none

Argument(s): INTEGER

Description

This keyword describes the number of scalar calibration terms. It is meant to be used in conjunction with field_calibration_terms, which describes the number of field calibration terms. The total number of calibration terms, both scalar and field, is given by calibration_terms. If only scalar calibration terms are specified, it is not necessary to specify the number of scalar terms explicitly: one can simply say calibration_terms = 5 and get 5 scalar terms. However, if there are three scalar terms and 2 field terms, then calibration_terms = 5 but scalar_calibration_terms = 3 and field_calibration_terms = 2.

Calibration terms are responses that are used with calibration methods in Dakota, such as least squares optimizers. Currently, each scalar term is added to the total sum-of-squares error function presented to the optimizer. However, each individual field value is added as well. For example, if you have one field calibration term with length 100 (e.g. a time - temperature trace with 100 time points and 100 temperature points), the 100 temperature values will be added to create the overall sum-of-squares error function used in calibration.
