.. _auto_curve_average_values:

*COMPUTE AVERAGE VALUE BASED ON TYPE*
=====================================

Computes a representative average value from a curve using one of several user-selectable averaging strategies (full range, partial range, first/last, until a threshold, or linear-fit-based). The resulting averaged curve replaces the original y-values with the computed constant. Use this worker to flatten or summarize a curve prior to material calibration or statistical analysis.

     - The input curve (vector of x/y pairs) to be averaged; must be provided before averaging is applied.

     - no

     - Selects the averaging strategy: 'no' returns the curve unchanged; 'yes' averages from 0.0 to end of plastic strain; 'yes_30f' averages over the first 30% of the plastic-strain range; 'yes_30b' averages over the last 30% of the plastic-strain range; 'first_last' uses the first and last values; 'avg_until' averages up to the threshold specified in value_type; 'avg_based_on_linear_fit' applies averaging only when the curve slope is near-zero (R²/slope thresholds configurable via value_type as 'R2:SlopeThreshold', defaulting to 0.9 and 0.001). Defaults to 'no'.
   * - Value based on type specified above
     - value_type
     - scalar

     - Auxiliary numeric or string parameter whose meaning depends on use_average_value: a scalar cutoff value when 'avg_until' is selected, or an 'R2:SlopeThreshold' string (e.g. '0.95:0.005') when 'avg_based_on_linear_fit' is selected; leave blank (defaults to 0.0) for all other averaging types.
