DOE PREPROCESSING WORKER¶
Applies pre-processing transformations to a DOE experiment table prior to simulation runs; currently supports Cockcroft-Latham damage curve generation, which derives a damage curve from a hardening curve and tensile failure strain for each simulation in the dataset. Use this worker when DOE experiment configurations require material damage pre-processing before solver submission.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Experiments | doe_experiments | dataset | — | ✓ | Dataset table of DOE experiment rows, each representing one simulation configuration; must contain at least the simulation ID column and the tensile failure strain column referenced in preprocessing_params. |
| Simulation Column Id | sim_id_column | scalar | id | ✓ | Name of the column in doe_experiments that holds the simulation identifier used to look up each simulation record; defaults to ‘id’. |
| Pre-processing Type | pre_processing_type | scalar | cockcroft_latham_damage | ✓ | Selects the pre-processing algorithm to apply; currently the only supported value is ‘cockcroft_latham_damage’, which computes a Cockcroft-Latham damage curve for each simulation. |
| Preprocessing parameters | preprocessing_params | textarea | — | Key-value map (textarea) supplying algorithm-specific parameters; for ‘cockcroft_latham_damage’ the required keys are tensile_failure_column (column name in doe_experiments), hardening_curve_id (curve ID to retrieve from the simulation), and damage_curve_id (curve ID to replace in the simulation). |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Simulations | pre_processed_info | dataset | Dataset of pre-processed simulation records, each containing the simulation ID, tensile failure strain, the original hardening curve, and the newly computed damage curve; consumed by downstream solver or DOE evaluation workers. |
