scalar_calibration_terms
Number of scalar calibration terms
Specification
Alias: None
Arguments: 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.
