CURVES SELECTOR FOR CALIBRATION¶
Selects a representative subset of curves for material calibration by evaluating each curve against user-defined criteria (slope, xmax, ymax, xatymax, integral) using a Pareto-front approach. Returns a dataset identifying the optimal curve(s) for downstream calibration workflows. Use this worker when you need to automatically pick the best-fit experimental curves from a pool of candidates.
When to use¶
Classification: process.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curves To Be Selected From | curvestobeselectedfrom | vector | — | Collection of input curves (vector/multi-curve) from which the best candidate(s) will be selected; typically experimental stress-strain or force-displacement curves supplied as a multi-value curve input. | |
| Selection Criteria | criteria | dataset | (complex) | Dataset table defining the selection criteria used in the Pareto-front evaluation; each row specifies a metric name (slope, xmax, ymax, xatymax, integral), the preferred direction (‘min’ or ‘max’), and whether to include it — defaults to ‘min’ for all five metrics if not provided. | |
| Type Of Data To Use | data_type | scalar | median | Determines whether the Pareto-front evaluation operates on ‘median’ (representative median curve, default) or ‘raw’ individual curve data; leave as ‘median’ unless raw replicate scatter must be preserved. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curves_get_curve_for_calibration_output_1 | curves_get_curve_for_calibration_output_1 | dataset | Dataset identifying the selected curve(s) that best satisfy the Pareto-front criteria, including the evaluated metric values, for direct use as calibration input in downstream material-parameter fitting workers. |
