Defining Boundary Layers Prior to Meshing

On the ribbon, click Layers

.

Click Select face

and pick the geometry surface(s) that you want to offset.

Alternatively, click Select body

and pick the entire solid body. Then, click Select target face

and pick the surfaces that you do not want to offset. This selection process may be simpler for more complex geometries.

If you are selecting faces for a fluid flow simulation, you typically want to pick faces that represent a wall boundary. For a structural simulation, you typically want to pick faces that represent a boundary where you anticipate high stress, and you want your mesh to have anisotropy so that you can capture the stress gradient near the boundary.

Tip: For complex models in which multiple faces require boundary layers, or to select internal faces, you may find the Inverse Selection option from the context sensitive (RMB) menu helpful.

For shell bodies, the selection processes are similar except you will select edges instead of faces to offset. Click Select edges

and pick the geometry edge(s) that you want to offset.

The following Options are available:

Choose a Layer growth method from the drop-down list. See Choosing a Layer Growth Method.
Depending on the Layer growth method chosen, set other layer options as described under Boundary Layer options.

Tip: You can set default Layer growth method and options using the SpaceClaim Options > Mesh panel. See Mesh options.

Click Complete

to create the boundary layer control.
