INSERT STRAIN-RATE CURVE INTO A SET

Inserts a new strain-rate curve into an existing set of strain-rate-tagged curves. Locates the existing curve at the closest strain rate, scales its Y values by the supplied factor (X is left unchanged), and inserts the result in ascending strain-rate order. Useful for active-learning DOEs where a new test point sits between two characterised strain rates.

Inputs

Label	ID	Type	Default	Required	Description
Curves	curves	vector	—	✓	Existing strain-rate-tagged set of curves (a CurveGroup with N curves). Order must match the strain_rates list.
Strain Rates	strain_rates	scalar	—	✓	Comma-separated list of N strain-rate values, one per curve, in the same order as the curves input. Example: ‘0.1, 1.0, 10’.
New Strain Rate	new_strain_rate	scalar	—	✓	Strain rate to add. The worker locates the closest existing strain rate, scales that curve, and inserts the new curve in ascending strain-rate order.
Y Scale Factor	sf	scalar	1.0		Multiplicative factor applied to the Y values of the closest matched curve before insertion. Use 1.0 to copy the curve unchanged. The X values are left untouched.

Outputs

Label	ID	Type	Description
Augmented CurveGroup	curve_add_strain_rate_curve_output_1	vector	Input CurveGroup plus one new curve inserted at the correct sorted position. Each output curve is named with its strain rate (e.g. ‘0.1’, ‘0.11’, ‘1’, ‘10’) so the augmented strain-rate list is recoverable from the curve names.
