When CFD changes the capital decision

CFD for manufacturing earns its keep when two or more mechanical options would purchase different equipment or duct routes. If the plant has already selected a package, simulation rarely changes the spend.

Start with the decision frame: what will we do differently if the model favors option A? Collect field boundary conditions that match operating modes operations actually run.

Deliverables should include assumptions, sensitivity, and a recommendation operations can challenge, not a gallery of streamlines.

When field data alone ranks options, stop. Models are tools under PE judgment, not deliverables for their own sake—and not an excuse for forced downtime.
