CREATES A HOLE EXPANSION RESPONSE TEMPLATE FOR DATA EXTRACTION¶
Creates a Hole Expansion Response template that defines the sensors and reference curves needed to extract punch-force, displacement, and blank-node data from a hole-expansion specimen simulation. Use this worker to register a named response template before running post-processing or curve-matching workflows.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| UIFTDS | import_from_file | file | — | Optional UIFTDS file used to pre-populate sensor definitions; leave empty to define sensors manually via the other inputs. | |
| Template Name | template_name | text | Generic Shear Tensile Template | ✓ | Human-readable name assigned to the new response template; defaults to ‘Generic Shear Tensile Template’ but should be set to a project-specific name to avoid collisions. |
| Reference Curve | ref_curve | vector | — | ✓ | Reference (experimental) curve used to compute curve-match error against the simulation result; provide as an XY vector in the units matching the selected ref_curve_type. |
| Reference Type | ref_curve_type | select | no | ✓ | Declares the axis convention of the reference curve — choose ‘fd’ (Force vs Displacement), ‘eng_ss’ (Engineering Stress vs Strain), ‘true_ss’ (True Stress vs Strain), or ‘dic_strain’ (DIC Strain vs Displacement) — must match the physical units of ref_curve. |
| Specimen PID | specimen_pid | text | 1 | ✓ | LS-DYNA part ID (PID) of the hole-expansion specimen blank whose elements are monitored for stress/strain extraction; defaults to 1. |
| Punch Node Id | punch_node | text | 1 | ✓ | Node ID of the single punch reference node used to track punch displacement and force; defaults to 1. |
| PNFPDC | punch_nodes | text | 10,20,30 | ✓ | Comma-separated list of exactly three punch node IDs (e.g. ‘10,20,30’) used to compute punch-force/displacement in the planar cross-section. |
| BNFBIDC | blank_nodes_inner | text | 40,50,60 | ✓ | Comma-separated list of exactly three node IDs located on the inner boundary of the blank hole (e.g. ‘40,50,60’) used to measure hole-edge displacement. |
| BNFBODC | blank_nodes_outer | text | 70,80,90 | ✓ | Comma-separated list of exactly three node IDs located on the outer boundary of the blank (e.g. ‘70,80,90’) used as the outer reference for displacement and strain calculations. |
| Delete Existing | delete_existing | select | no | Controls whether a pre-existing template with the same name is deleted before creation; set to ‘yes’ to overwrite, default ‘no’ will raise an error if the name already exists. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Template Id | template_id | integer | Integer database ID of the newly created Hole Expansion response template object (dataType: responsetemplate), used as input to downstream post-processing or curve-matching workers. |
