Using Mesh Regions

If parts of a design are geometrically complex or require finer control for accuracy, users can designate those regions as mesh regions and enhance simulation precision. Mesh regions can be partitioned, and each partition can be simulated sequentially or in parallel to improve accuracy. Complete these steps to activate these features and manipulate mesh partitions.

1. From the Layout Editor, select a component to designate as a mesh region.

   

2. Do either of the following to open the Mesh Region Dialog window:

• From Draw, select Mesh Region > Create.

  

• Right-click within the Layout Editor and select Mesh Region > Create.

  

3. From the Mesh Region Dialog window, make any other appropriate selections and enter a number in the Partitions area (e.g., 5).

   

4. Click OK to close the Mesh Region Dialog window and the partitions will appear in the Layout Editor.

   

5. Click+drag on partition lines to drag them or select a line and use the handles that appear to transform the partition(s), as necessary.

   

6. If necessary, add a new partition line by doing the following:

   1. From the Layout Editor, select the mesh region. Then right-click and select Mesh Region > Add a partition line.

      

   2. Click the edge of the mesh region to start a new line.

      

   3. Drag the mouse to another edge and click again to see the new line segment.

      

   4. Repeat step c, as necessary, to create more line segments, or press Enter to create the new partition line.

      

7. When the mesh region is complete, navigate to the Project Manager window. Expand the Project Tree > Active Design Folder (e.g., EMDesign1) > Analysis. Then right-click the Setupn and select Generate Mesh.

   

8. From the Project Manager window, right-click Setupn and select Properties.

   

9. From the Setup window, navigate to the Adaptive Solutions area and click Use Mesh Region to activate the drop-down menu and the Parallel Refinement check box.

   

10. Select the appropriate mesh from the drop-down menu (e.g., meshregion_6).

11. By default, mesh partitions are simulated sequentially for more accurate results. Check the Parallel Refinement box and the partitions will be simulated in parallel.

The procedure is complete.
