ENSURE FIRST YIELD GT ZERO¶
Inspects a set of stress-strain (or similar yield) curves and ensures that the first yield point on each curve has an x-value strictly greater than zero, shifting or trimming the curve as needed. Use this worker to sanitize material curves before calibration or solver input so that invalid zero-or-negative initial yield values do not cause downstream errors.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curves To Be Operated On | curvestobeoperatedon | vector | — | One or more input curves (e.g., stress-strain or force-displacement) whose first yield point will be checked and corrected to be > 0; accepts multiple curve objects and is optional — if omitted, no operation is performed. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curves_ensure_first_yield_gt_zero_output_1 | curves_ensure_first_yield_gt_zero_output_1 | vector | The corrected curves with the first yield point guaranteed to be strictly greater than zero on the x-axis, returned in the same vector format as the input. |
