CLIP CURVE TO DELAY NEGATIVE Y-VALUE¶
Clips one or more curves by adjusting the slope of the tail segment so that the extrapolated y-value crosses zero only after a specified multiple of the original x-maximum, effectively delaying the onset of negative y-values. Use this worker to post-process failure or damage curves where a premature negative y-intercept would cause solver instability or unrealistic behaviour.
When to use¶
Classification: process.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curve | curve | vector | — | One or more input curves (x/y vector pairs) whose tail slope will be adjusted to delay the y=0 crossing; accepts multiple curves in a single pass. | |
| Segment Size In Terms Of Percentage Of Points | per_p | scalar | 0.05 | Tail-segment size expressed as a fraction of the total number of curve points (e.g. 0.05 = last 5 % of points); default 0.05 is a reasonable starting value for most curves. | |
| Max Limit | max_limit | scalar | 5 | Multiplier applied to the curve’s x-maximum: the adjusted slope ensures the extrapolated y-value turns negative no sooner than max_limit × x_max (e.g. default 5 means the zero-crossing is pushed past 5× the original x-range). |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Clipped Curves | curves_clip_o | vector | Tail-adjusted output curves in the same x/y vector format as the inputs, with slopes modified so the y=0 intersection is delayed beyond max_limit × x_max. |
