Calculator workflow modes
Every engineering module exposes three workflow modes in the header. They change how the primary action button behaves and which panels appear — they do not change the underlying physics.
Auto-design
Purpose: Size from your targets instead of starting from a fixed geometry.
- Enter loads, limits, and safety factors (design targets) in the inputs panel.
- Click Auto-design — the module ranks catalog or solver candidates, applies the best match, then validates.
- Review updated geometry, utilization, charts, and code checks in the results.
Maturity note: On modules marked workflow-only, Auto-design changes the button label but does not auto-size yet — use Validate for analysis. On catalog-backed modules, Auto-design ranks catalog entries. On solver-backed modules, it runs a sizing search and applies the best candidate.
Validate
Purpose: Run the forward solver on the geometry and loads already in the form.
- Enter geometry, loads, material, and supports in the inputs panel.
- Click Validate (or Calculate) to run the forward solver.
- Review numeric results, plots, and engineering checks for your design standard.
This is the default mode when you open a module.
Compare
Purpose: Browse ranked sizing options before committing to one size.
- Open Sizing candidates & reference to see ranked catalog or solver options.
- Click Apply on a row to load that size into the form (switches to Validate).
- Run Validate again to confirm the chosen option with full physics and code checks.
Application preset
The Application preset dropdown (when shown) sets screening context for your design standard: service factors, deflection limits, and reference standards. It does not replace module-specific inputs — it seeds design targets and, on some modules (e.g. bearings), catalog filters.
Document status & export quality
Before exporting a PDF or sharing results, confirm the calculation is complete:
| Item | Meaning |
|---|---|
| Inputs complete | All required fields have valid values. |
| Solver run | You have clicked Calculate / Validate at least once. |
| Checks reviewed | Engineering checks in the results panel have been read. |
| Charts included | Result plots are populated (where applicable). |
| Assumptions noted | Limitations from the module reference doc are understood. |
The export dialog uses this checklist internally. Full assumptions and limitations for each module are in module documentation.
