DROP POSITIVE POINTS¶
Filters a curve by removing all data points where the Y-value is positive, retaining only zero and negative values. Use this worker to isolate compressive or negative-phase portions of a time-history or load curve.
When to use¶
Classification: process.
Tagged: curve, drop, filter, negative, positive, time-history, transform.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curves | curve | vector | — | Input curve whose positive Y-value points will be removed; accepts a single X-Y vector curve (e.g. a force or displacement time-history). Optional — leave unconnected only if the curve is injected upstream. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_drop_if_positive_output_1 | curve_drop_if_positive_output_1 | vector | Filtered output curve containing only the points from the input curve where the Y-value is zero or negative; same X-Y vector format as the input. |
