Add a Boundary Layer Properties node (
) to specify the location of the boundary layers and the properties, such as the number and thickness of the boundary layers.
By default, one Boundary Layer Properties node is added as a subnode to a Boundary Layers node. To add additional nodes, right-click a 2D or 3D
Mesh node and select
Boundary Layers Properties;
then enter the properties using the following sections:
Define the boundaries where you want boundary layers. Choose Manual in the
Selection list to select the boundaries in the
Graphics window or choose
All boundaries to select all boundaries.
The default Boundary layer stretching factor is 1.2. This field is used to specify the increase in thickness between two consecutive boundary layers as a scaling factor; for example, entering
1.3 means that the thickness increases by 30% from one layer to the next.
