.. _auto_curves_get_damage:

*GET AMOUNT OF DAMAGE*
======================

Computes a scalar damage metric for one or more input curves by sampling a trailing window of points and quantifying the deviation or cumulative response in that region. Use this worker when you need a quick, comparable damage index from time-history or load curves — larger output values indicate greater damage.

Inputs

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

     - Type
     - Default
     - Required
     - Description
   * - Curve
     - input_curve
     - vector
     - —
     - 
     - One or more input time-history or load curves (vector) to be evaluated for damage; accepts multiple curves simultaneously.
   * - Ratio Of Points From End
     - per_points_from_end
     - scalar
     - 0.2
     - 
     - Fraction of the total curve points sampled from the tail end to compute the damage metric (dimensionless, 0–1); default 0.2 means the last 20 % of points are used — increase for longer damage windows, decrease to focus on the very end.

Outputs

   * - Label

     - Description
   * - Damage
     - curve_get_damage_output_1
     - keyvalue
     - Key-value map of damage scores for each input curve; dimensionless scalar — larger values indicate greater damage accumulated in the sampled trailing window.
