Use Edge () to mesh edges in 1D, 2D, and 3D. This is useful not only for intervals in 1D, but also for applications where the physics is solved on edges in 2D and 3D, as seen in Figure 8-54.

You can control the number of elements and the distribution of elements in the edge mesh by using Size and Distribution nodes.

To add an Edge node, select edges in the Graphics window, then choose one of the following:

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:

Use the Smooth across removed control entities setting to smooth the transition in element size across removed control entities. Use Automatic (default) to let the algorithm decide if to apply smoothing or not. Smoothing will be applied if, for example, 2D domains adjacent to edges with a removed vertex contain triangular elements only. When set to On, the mesher adjusts the sizes of the mesh elements to get a smoother transition from large to small elements by adjusting the locations of the mesh vertices on the entity that is removed. Select Off to not adjust the mesh. When set to On, 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 for the mesh vertices to be smoothed.
