Edit Edge Density and Element Size

Use the General 2D Mesh: Density tool to edit element density and size along surface edges.

Before you begin, use the General 2D Mesh: Create tool to define a meshing area by selecting surfaces, and create an initial mesh.
The local edge element size approximation is based on edge density value and length. Hence, it can vary slightly for two edges with the same density value.
  1. From the Mesh ribbon, click the General 2D Mesh > Density tool.

    Figure 1.
  2. Optional: On the guide bar, click to define surface mesh options.
  3. Left-click to select the edge(s) to modify.
  4. In the microdialog, click the icon to switch the value being defined to either element density or element size.
  5. Edit element density or size in the following ways:
    • Increase individual edge values by holding Ctrl while left-clicking on an edge; decrease individual edge values by holding Ctrl while right-clicking on an edge.
    • Scroll edge values by holding Ctrl while scrolling the mouse wheel up and down. Hovering directly over an edge will only modify that edge; hovering over empty space will modify all selected edges.
    • Specify an edge value in the microdialog and press Enter. If multiple edges are selected, a common value will be applied. If multiple edges with different edge values are selected, use the arrows in the microdialog to modify individual edge values simultaneously, without applying a common value.
  6. On the guide bar, click Update
Tip: Clear your selection by left-clicking in empty space.
