s Kills Convection · Orthogonality Kills Diffusion

Added: 2026-05-28

[00:00:00]Each mesh quality metric attacks a different part of the solver. Skewness corrupts gradient reconstruction, which smears convective fluxes.

[00:00:09]Your flow features get artificially diffused. Orthogonality corrupts the Laplacian approximation, which destabilizes the pressure equation in simple and PISO solvers.

[00:00:20]Mass conservation errors and pressure oscillations follow.

[00:00:24]Aspect ratio creates directional bias all. Great resolution in one direction, terrible in another.

[00:00:30]Know which metric matters most for your flow physics.
