FEM BILL OF MATERIALS¶
Builds a bill of materials from an LS-DYNA model. For every part it reports material class, section thickness, area, volume, mass and density; connection count, area and types (weld, rigid, adhesive, tied); detected features (holes, slots, slits); a geometric part class (panel, rail, wheel, tire, bracket, casting…); and the assembly it belongs to (body-in-white, front/rear suspension, bumper system, wheels & tires, powertrain, closures…). Optionally renders a per-part thumbnail in LS-PrePost.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Model files | input_files | file | — | ✓ | The LS-DYNA model: the master deck plus its include files. Can be fed from a simulation’s files or an uploaded set. |
| Master file pattern | main_file_pattern | text | — | Optional substring to pick the master deck among the inputs (e.g. ‘main’ or ‘master’). Defaults to the first file. | |
| Solver | solver | select | lsdyna | Solver format of the model. LS-DYNA is currently supported. | |
| Generate part thumbnails | generate_thumbnails | select | no | When Yes, renders a per-part image in LS-PrePost and includes it as a thumbnail column (requires LS-PrePost on the server). | |
| Include connections dataset | include_connections | select | no | When Yes, also returns a Connections dataset: one row per connection found in the model (weld / bolt / clip / insert / rigid / adhesive) with the parts joined, centroid, footprint area, mass, volume and stiffness. | |
| Include loads & boundary dataset | include_loads | select | no | When Yes, returns a Loads & Boundary dataset listing each *LOAD_, *BOUNDARY_ and *INITIAL_ card with its target id. | |
| Include parameters dataset | include_parameters | select | no | When Yes, returns a Parameters dataset with every *PARAMETER name, value and how many times it is referenced. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Bill of Materials | bom | dataset | One row per part with material, thickness, area, volume, mass, connections, features, geometric part class and assembly. |
| Connections | connections | dataset | One row per connection (opt-in): type, joined parts, centroid, footprint area, mass, volume and stiffness. |
| Loads & Boundary | loads | dataset | Opt-in: each load, boundary condition and initial condition with its target id. |
| Parameters | parameters | dataset | Opt-in: every *PARAMETER name, value and reference count. |
| BOM Summary | summary | keyvalue | Part count, total mass, and counts by assembly and material. |
| Part Count | part_count | scalar | Number of parts in the model. |
