10 Boundary Layers
Boundary layer meshing in Coreform Cubit™ is best accessed via the GUI. To create a boundary layer:
On the Command Panel, click on Mesh and then Boundary Layer.
Click on the Create action button.
Select System Assigned ID or manually enter an ID.
- On the Settings tab:
Enter the appropriate size for the first row in the boundary layer
Enter a value for the Growth Factor
Specify the Number of Layer
Optionally select Internal Continuity
Figure 539 shows the Settings panel.
First row(a): the height of the first layer in the boundary layer
Growth Factor(b/a): the factor by which each layer grows
Number of Layers: the number of layers that make up a boundary layer
Internal Continuity: continuity flag for boundary layers. If on, all intersections are a side type.
- On the Association tab:
select Curve for 2D boundary layers or Surface for 3D boundary layers.
- For 2D boundary layers:
In the Curve ID(s) field, enter the curve ID(s) where the boundary layer(s) begins.
In the Surface ID field, enter the surface ID that contains the boundary layer(s).
Click Add to add the curves to the boundary layer(s).
Click Create to create the boundary layer(s).
- For 3D boundary layers:
In the Surface ID(s) field, enter the surface ID(s) where the boundary layer(s) begins.
In the Volume ID field, enter the volume ID that contains the boundary layer(s).
Click Add to add the curves to the boundary layer(s).
Click Create to create the boundary layer(s).
Figure 540 shows the Association panel.
For 2d boundary layers, a curve/surface pair is given to create a boundary layer starting from a curve and growing out on the given surface.
For 3d boundary layers, a surface/volume pair is given to create a boundary layer starting from a surface and growing out on the given volume.
