CLIP CURVE TO DELAY NEGATIVE Y-VALUE¶
Clips a curve’s trailing segment so that its extrapolated slope crosses y = 0 only after a specified multiple of the original x-maximum, effectively delaying the apparent failure point. The tail slope is refit using a percentage-based segment of the curve’s last points. Use this worker to push a material or structural curve’s zero-crossing further out in time/displacement without altering the early response.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curve | curve | vector | — | Input curve (x-y vector) whose tail slope will be adjusted so that the y = 0 crossing is delayed; must be a standard d3VIEW curve vector — leave unconnected only if passing directly via workflow context. | |
| Segment Size In Terms Of Percentage Of Points | per_p | scalar | 0.05 | Fraction of total curve points used to define the trailing segment for slope fitting (e.g., default 0.05 means the last 5% of points); increase for a smoother/more stable slope estimate, decrease to use only the very last portion. | |
| Max Limit | max_limit | scalar | 5 | Multiplier on the original x-maximum beyond which the extrapolated y-value must become negative (default 5 means y < 0 is enforced beyond 5 × x_max); increase to delay failure further, decrease to allow an earlier crossing. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Clipped Curve | curve_clip_o | vector | Modified curve with the tail slope adjusted so that the zero-crossing is deferred to at least max_limit × x_max; all points up to the clip point are unchanged from the input curve. |
