Summary: Control the rate at which enhancement layers grow
Flag:
mesh_enhance_gradation A
A = Growth factor. For example, to grow the layers by 10%, specify a value of 1.1.
Description:
This setting controls how the enhancement layer thickness grows. In previous versions, the layer growth rate was not a user-defined quantity. As the number of enhancement layers increases, the layer thickness became more uniform. This control allows the layers nearest the wall to be smaller than those closest to the neighboring unstructured elements.
Use this control to improve the accuracy of heat flux at the wall and with the SST turbulence model.
