Ansys Meshing | Inflation
Written by cfd.ninja
Automatic inflation saves you from selecting wall faces one by one. Instead of picking each boundary, you let Ansys Meshing decide which faces receive prism layers, either under program control or from the Named Selections you defined earlier in the geometry.
The result is the same as manual inflation: stacked prism cells that resolve the boundary layer, where the height of the first layer sets the y+ your turbulence model sees. Estimate that height with the Y+ calculator before meshing, not after.
It is worth preparing Named Selections from the start of a project. They make the inflation setup repeatable, and they carry over to the solver as named boundaries.
In this tutorial, you will learn to use the Inflation tool in Ansys Meshing to control the boundary layer mesh near walls for more accurate CFD simulations.
