Number of scalar calibration terms
Alias: none
Argument(s): INTEGER
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 sumofsquares 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 sumofsquares error function used in calibration.
