Edge
Add an Edge node () to mesh edges. You can control the number of elements and the distribution of elements in the edge mesh by using Size and Distribution nodes.
To create an edge mesh:
•
In the Mesh ribbon toolbar (Windows), from the Generators>Boundary () menu choose Edge.
•
From the Mesh contextual toolbar (macOS and Linux), choose Edge from the Boundary menu () (3D components) or click Edge (2D or 1D components).
•
Right-click a Mesh node and choose More Operations>Edge.
Then enter the properties using the following sections:
Edges (3D) / Boundaries (2D) / Domains (1D)
To define the edges where you want a create a mesh, first choose the level of the geometric entities from the Geometric entity level list:
•
Choose Entire geometry to specify an edge mesh for the entire geometry.
•
Choose Remaining to specify an edge mesh for remaining, unmeshed edges.
•
Choose Edge (3D), Boundary (2D), or Domain (1D) to specify the edges for which you want to create a mesh. Choose Manual in the Selection list to select the edges in the Graphics window or choose All edges (3D), All boundaries (2D), or All domains (1D) to select all edges.
Control Entities
Select the Smooth across removed control entities check box to smooth the transition in element size across removed control entities. You can specify the number of smoothing iterations in the Number of iterations field. In the Maximum element depth to process field you can specify the maximum element depth, from the boundary layer interface, for the mesh points to be smoothed.
