*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

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20 20 20

   * - Label

     - 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

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20

   * - 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.
