We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

y+ value around the S809 airfoil

  Hello everyone,
  I am currently working on generating a structured mesh for the S809 airfoil profile using the Ansys Student version (detailed images of the mesh are attached). However, I am encountering issues with maintaining an appropriate y+ value.
  As I am using the k-omega SST turbulence model, it's essential to achieve a y+ value of 1 or less. For a y+ value of 1 in my case, the corresponding wall-normal spacing (y) should be 2.34e-5. Despite increasing the number of elements along various edges of the mesh, the maximum y value I can achieve is 5 e-4.
  Is there a way to reach the required y value without using inflation layers, as I am working with a structured mesh?

  Use inflation - there's a reason they're in the Meshing tools. No need to use a structured (mapped) mesh.
