CFD Verification Workflow

Combine mesh refinement, conservation, timestep sensitivity and validation/reference comparison into one evidence screen with explicit, editable tolerances.

EVIDENCE, NOT A CHECKBOX

Grid convergence is only one part of CFD credibility.

The workflow puts discretization, conservation, timestep and validation evidence side by side. Tolerances remain editable because acceptable uncertainty depends on engineering risk.

Grid sequence. Estimate observed convergence order and GCI.

Conservation. Check mass and energy balance.

Transient resolution. Check timestep sensitivity independently of mesh refinement.

Validation. Numerical convergence does not prove physical accuracy.
