Preview a 2D box culvert (Eurocode)
culvert_previewRead-only
Step 1 of a 2D box culvert built from inputs (Eurocode). Not for bridge decks (skew_grillage). Validates a 2D Culvert project with the plugin's own Eurocode core and returns what it would build: nodes, elements, soil springs, basic load cases (traffic unit cases), the EN 1990 Annex A2 combination counts (ULS, SLS characteristic, quasi-permanent) and the nested CIVIL NX combinations, check locations, earth-pressure basis (K0 / PD 6694-1 Annex B / cl 9.4 K*) and derived geometry. Needs no model.
