Seven CFD meshing mistakes
Explore the issues, see their numerical impact, and learn how to correct them.
01 · Poor cell quality
See how skewness, non-orthogonality, and distortion damage stability and accuracy.
02 · Insufficient refinement
Identify where coarse cells fail to capture curvature, wakes, and steep solution gradients.
03 · Ignoring boundary layers
Connect inflation layers, wall treatment, and solved y⁺ to reliable wall predictions.
04 · Abrupt size transitions
Explore why sudden jumps in neighboring cell size increase interpolation error.
05 · Chasing cell count
Replace ‘more cells’ with targeted resolution, quality, and quantities of interest.
06 · Skipping grid convergence
Use systematic refinement and GCI to estimate spatial discretization uncertainty.
07 · Trusting statistics alone
Look beyond summary metrics and locate the worst cells in critical flow regions.
