GET IDS FROM SET¶
Reads an LS-DYNA input deck and returns the IDs of all shell elements whose centroids fall within a specified search radius of a given XYZ coordinate, optionally filtered by part ID. Use this worker to programmatically locate shell elements near a point of interest for post-processing, set creation, or targeted result extraction.
When to use¶
Tagged: coordinates, element_ids, lsdyna, mesh, pid, shell, spatial_search.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| LSDYNA Input File | input_file | file | — | ✓ | LS-DYNA input deck (keyword format, e.g. .k / .key / .dyn) containing the mesh definition from which shell element geometry will be read. |
| Coordinates | coords | text | — | ✓ | Comma-separated X, Y, Z coordinates (e.g. ‘10.5,0.0,-3.2’) defining the centre point of the spatial search; units must match the model units. |
| Pid | pid | text | 1 | Part ID used to restrict the search to shells belonging to a specific part; defaults to 1. Leave at default only if part 1 is the target part. | |
| Search Radius | search_radius | text | 0.1 | Radial distance (in model units) around the target coordinates within which shell element centroids are considered a match; defaults to 0.1 — increase for coarser meshes or wider selections. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Shell Ids | shell_ids | dataset | Dataset containing the integer IDs of all shell elements whose centroids lie within the specified search radius of the given coordinates, filtered by the specified part ID. |
