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.

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.
