CONNECTION TOPOLOGY AGGREGATOR¶
Aggregates raw connection edges into part-to-part pairs with counts, dominant types, total mass / length / stiffness. Filters to the top-N highest-degree parts and applies a minimum-count threshold so very large models (thousands of edges) render as a tractable graph. Pipe normalized edges from ConnectionTopologyParserWorker into this.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Edges | edges | dataset | — | Normalized connection edges (output of ConnectionTopologyParserWorker.edges). | |
| Top-N Parts | top_n_parts | integer | 150 | Keep only the top-N parts by degree to limit graph size. | |
| Min Pair Count | min_pair_count | integer | 1 | Drop part-pairs with fewer than this many connections (set to 2+ to hide one-off ties for cleaner view). | |
| Type Filter | type_filter | string | — | Comma-separated connection_type whitelist (e.g. ‘CONSTRAINED_SPOTWELD,ELEMENT_BEAM’). Empty = all types. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Pair Edges | pair_edges | dataset | Aggregated edges — one row per unique part-pair: {source, target, count, types, total_mass, total_length, total_stiffness}. |
| Visible Edges | visible_edges | dataset | Subset of pair_edges restricted to top-N parts (ready for graph rendering). |
| Top Parts | top_parts | dataset | Top-N parts sorted by degree. |
| Stats | stats | dataset | Aggregation counts + filter parameters. |
