Create Edges
Use a Create Edges node () to create edges in a component without geometry.
To add a Create Edges node to a 2D component, right-click the Mesh node and select Create Edges. For a 3D mesh, it is available from the Create Entities menu () on the Mesh ribbon or by-right clicking the Mesh node. You can add a Create Edges node when the geometry is empty but the mesh includes either an Import node or a Create Vertices node.
Enter the properties for the Create Edges node using the following sections:
Starting Vertices, End Vertices
To create edges, select vertices in the Starting Vertices and End Vertices sections. Edges will be created from vertices in the selection in Starting Vertices to vertices in the selection in End Vertices. From each vertex in the selection in Starting Vertices, edges will be created to the closest vertices in the selection in End Vertices.
Element Size
To specify the size distribution of the edge mesh, select one of the methods from the Size distribution type list:
•
Select Element size (the default) to specify the maximum element size (SI unit: m), which you enter in the Maximum element size field. The value is a relative number (default: 0.1 in 3D and 1/15 in 2D). This value is multiplied with the size of the bounding box.
•
Select Fixed number of elements to use a fixed number of mesh elements, which you enter into the Number of elements field (default: 1).
•
Select Explicit distribution to use an explicit, user-defined element distribution. To define the distribution of mesh elements, enter a vector-valued expression defining a strictly increasing sequence of nonnegative numbers (using comma-separated numbers) in the Relative placement of vertices along edge field, specifying the relative arc length values of the mesh vertices along the edge or boundary. Select the Reverse direction check box to reverse the direction of the explicit distribution.
•
Select Predefined distribution to specify properties of a predefined distribution method that can be a Geometric sequence (exponentially increasing or decreasing element size) or an Arithmetic sequence (constant difference in size between neighboring elements), which you choose from the Growth formula list. In addition, specify values in the Number of elements and Element ratio fields to determine the number and ratio of elements in the distribution. Select the Symmetric distribution check box to make the predefined size distribution symmetric. Select the Reverse direction check box to reverse the direction of the predefined distribution.
