Purpose

Add near-wall prism layers to better resolve gradients next to walls.

Steps

  1. Enable Wall treatment in Mesh.

    Wall treatment controls

  2. Use surface mesh settings where individual walls need explicit layer controls.

    Wall treatment controls

  3. Generate the mesh and inspect the layers and mesh quality near walls.

Inputs and units

Input or valueMeaningUnits
Wall treatmentEnables the near-wall meshing treatment.On / off
Layer controlsLayer count, first-layer thickness, and growth ratio are set in surface mesh settings.Count, length, dimensionless ratio

Limitations

  • Complex corners and narrow gaps can limit layer generation and increase meshing time. Layer settings alone do not establish adequate near-wall resolution.
