CFD Mesh Quality Checklist

About this resource

This ten-page checklist gives CFD analysts a consistent way to review a mesh before a solve. It covers the fluid domain and geometry, surface mesh closure and quality, boundary-layer height and coverage, volume mesh metrics, physics alignment and solver readiness.

Each section lists the checks, typical acceptance values and space to record the actual result and the corrective action. A quality metric reference explains what orthogonal quality, skewness, aspect ratio, Jacobian ratio, y+ and growth rate measure, and why each one matters.

The final pages provide a mesh review record, a corrective-action log, a sign-off block, the assumptions and limitations, and the licence. It is written to be used on a real project, not read once and filed away.

The checklist is vendor-neutral and applies to general-purpose finite-volume CFD. Target values are common engineering practice, not universal acceptance criteria; always follow the solver vendor's guidance and support any decision with a mesh independence study.

Prerequisites and technical context

Intended audience

working-engineer, engineering-team, early-career-engineer, student

Prerequisites

• Basic familiarity with finite-volume CFD
• A mesh that can be inspected in the meshing tool or solver

Unit systems

• SI and dimensionless metrics

Assumptions

• General-purpose finite-volume CFD
• Cell-centred or vertex-centred solver
• Target values are common engineering practice, not universal acceptance criteria
• Vendor-specific metric definitions may differ

Technical notes

• Wall-function models typically need 30 ≤ y+ ≤ 300; resolved boundary layers need y+ ≤ 1.
• Boundary-layer growth rates of 1.10–1.20 are common practice.
• Orthogonal quality and skewness definitions vary between vendors; record the tool and version used.
• A mesh independence study is the only direct evidence that a mesh is adequate for a result.

References

• No external standards or references listed.

Scope and limitations

Included

• Geometry and fluid-domain checks
• Surface mesh coverage, closure, normals and quality
• Boundary-layer height, growth, coverage and y+
• Volume mesh orthogonal quality, skewness, aspect ratio and Jacobian
• Physics alignment and solver-readiness checks
• Quality metric reference, review record, corrective-action log and sign-off

Not included

• Boundary-condition selection and verification
• Material data and turbulence model selection
• Convergence monitoring and validation
• A mesh independence study or uncertainty quantification
• Software-specific step-by-step instructions

Limitations

• Target values are guidance, not a substitute for vendor documentation or project requirements.
• A mesh that passes every metric can still produce a wrong answer.
• Use the checklist as a review record, not as certification of accuracy.

Author and review information

Author / publisher: Engineering Resources

Review status: Author checked

The checklist was assembled from established CFD mesh-review practice. Metric definitions and target ranges were cross-checked between common finite-volume solver conventions and are presented as guidance rather than universal limits.

Review scope: Formulas, worked defaults and stated assumptions were checked against the classical equations named on each sheet. No independent third-party review was commissioned.
