CREATES STUDY FOR CURVE EXTRAPOLATION EXPERIMENTS¶
Creates a DOE study for curve extrapolation experiments by launching a set of simulation runs from a source simulation, applying a chosen hardening-law extrapolation model (Swift, Voce, Hockett-Sherby, etc.) to extend a flow-stress curve beyond the measured strain range. Use this worker to systematically explore extrapolation parameter space or to generate a single baseline extrapolated curve for downstream material calibration workflows.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| NOTS | study_name | scalar | — | ✓ | Unique name for the new DOE study as it will appear in the d3VIEW studies registry; must be a non-empty string. |
| DOTS | study_description | text | — | ✓ | Human-readable description of the study’s purpose and scope; stored as free-text metadata on the study record. |
| Simulation | source_simulation_id | remote_lookup | — | ✓ | Reference to the baseline simulation whose setup is cloned for each DOE experiment; selected via remote simulation lookup. |
| Effective Curve | effective_curve | vector | — | ✓ | Input flow-stress (effective stress vs. effective plastic strain) curve to be extrapolated, supplied as an X-Y vector pair. |
| Experiments | experiments | dataset | — | ✓ | Dataset table defining the DOE experiment matrix — each row specifies one set of extrapolation parameter values to be evaluated. |
| Map Parameters | map_parameters | dataset | — | ✓ | Dataset mapping extrapolation model parameter names to their corresponding simulation/keyword variables so the worker can inject values into each run. |
| Extrapolation Type | extrapolation_type | select | swift | ✓ | Hardening-law model used for curve extrapolation; choose from Swift (default), Voce, Hockett-Sherby, Modified Hockett-Sherby, or Stoughton-Hoon. |
| Last Strain | last_strain | text | — | Maximum effective plastic strain value to which the curve is extrapolated; leave blank to use the model’s natural termination point. | |
| Increment | increment | text | — | Strain increment (step size) used when generating the extrapolated curve points; leave blank to inherit the source curve’s spacing. | |
| Curve Id | curve_id | text | — | Identifier of the specific curve within the source simulation to extrapolate; leave blank if the simulation contains only one effective curve. | |
| Run Baseline Only | baseline_only | select | yes | ✓ | When set to ‘Yes’ (default), only the baseline experiment is executed and the full DOE matrix is skipped; set to ‘No’ to run all experiments defined in the experiments dataset. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| study | study_id | integer | Integer primary key of the newly created DOE study record in the d3VIEW database; used by downstream workers to reference this study. |
| simulations | simulations | dataset | Dataset listing all simulation runs launched under the study, including their IDs, status, and parameter assignments for each experiment. |
| curves | curves | vector | Collection of extrapolated flow-stress curves (one per experiment) returned as X-Y vectors, ready for plotting or material card authoring. |
