# Simulation validation report template

Use one copy per model revision and decision. Replace bracketed prompts with evidence; mark unavailable information explicitly.

## 1. Decision and scope

- Decision supported by this model:
- Quantity of interest and units:
- Operating envelope and excluded conditions:
- Acceptance criterion and reason for the threshold:
- Consequence of an incorrect decision:

## 2. Model configuration

| Item | Value / source / revision |
|---|---|
| Geometry | |
| Material and fluid properties | |
| Boundary and initial conditions | |
| Correlations or turbulence / multiphase models | |
| Controls and imposed schedules | |
| Solver version and settings | |

### Assumptions and limitations

1. [Assumption; evidence; expected direction of bias]
2. [Assumption; evidence; expected direction of bias]

## 3. Verification

- Conservation checks (mass, energy, momentum as applicable):
- Residual or nonlinear convergence criteria:
- Mesh/discretization comparison and quantity of interest:
- Time-step or solver-tolerance comparison:
- Code or implementation checks:

| Case | Resolution / tolerance | Output | Relative difference | Notes |
|---|---:|---:|---:|---|
| Baseline | | | | |
| Refined 1 | | | | |
| Refined 2 | | | | |

## 4. Calibration and independent validation

List calibration cases separately. A case used to tune parameters is not an independent validation case.

| Case | Calibration or validation | Operating point | Measured ± uncertainty | Predicted | Error | Notes |
|---|---|---|---:|---:|---:|---|
| | | | | | | |

- Bias and spread across the envelope:
- Outliers and physical explanation:
- Measurement traceability and uncertainty:

## 5. Sensitivity and uncertainty

| Input | Nominal | Plausible range | Source | Output change / rank |
|---|---:|---:|---|---|
| | | | | |

- Inputs that can reverse the decision:
- Extrapolation beyond available evidence:
- Recommended additional test or measurement:

## 6. Decision record

- Does the model meet the stated criterion? [Yes / No / Conditional]
- Restrictions on use:
- Reviewer, date, model revision:
- Revisit this conclusion when:
