Redistribution

The adapter has the ability to redistribute the boundary layer mesh.

Capabilities:
  • Mesh wall spacing adjusted according to y+ values
    • Meets requirements of turbulence models
  • Multiple element types supported
    • Hexahedra
    • Prisms

Diagram:
The left hand picture shows a constant thickness boundary layer mesh before redistribution. The right hand picture shows a redistributed mesh with the mesh being pulled closer to the surface at the leading edge and pushed away from the surface downstream.

Aircraft Surface y+ Redistribution

These pictures show the boundary layer mesh for the nose of an aircraft before and after redistribution. The initial mesh produced a y+ value much higher than the desired value. After redistributing the mesh, the final y+ value was lowered to near the goal.
