Open this dialog by clicking Auto in the 2D Boundary Layer Mesh
dialog.
Use Minimum (Core/Boundary-Layer) thickness ratio to specify the ratio between boundary
layer thickness and tetra core. This value must be more than zero, but decimal values are
accepted. The higher this value, the more the boundary layer elements will be compressed to
keep the core open. Figure 1.
Use BL thickness at corners: '0.1,1'Thinner, '1,10'Thicker to define the boundary layer
behavior in corners. The smaller this value is, the smaller the thickness of the boundary
layer at corners will be relative to the nominal total boundary layer thickness. The image
below shows the effects on the same model using values of one and five. Figure 2.
The Generate BL Thickness ratio button generates the BL thickness scaling factors to be
utilized in the BL generation step.
If you wish to display contours of the Boundary Layers' Thickness Ratio, click the Contour
of BL Thickness ratio button.
