Workflow
Where OpenFlows fits in delivery
- 01
Brief & data
Geometry, loads, codes and the decision to support.
- 02
Modeling
Build the coordinated model everyone downstream works from.
- 03
Analysis
Check behaviour under load against the governing codes.
- 04
Simulation
Test real-world behaviour before anything is built.
- 05
Deliverables
Results, drawings and reports reviewed by an engineer.
