Perform Box Refinement

Use the Refine: Box tool to refine elements enclosed inside a box.

1. From the Elements ribbon, click the Refine > Box tool.

   
   
   Figure 1.

2. Optional: On the guide bar, click to define refinement options.
3. Select the center node to start the uniform mesh refinement.
   A refinement box is created.
4. Adjust the size and shape of the refinement box by clicking on a face and dragging the slider or inputting a value in the microdialog.
   The refinement box determines the constant refinement zone. Elements inside this box should be the same size.
5. Click Transition: Elements on the guide bar.
   A transition box is created.
6. Adjust the size and shape of the transition box in a similar manner to the refinement box.
   The mesh will be transitioned to match the initial mesh.

   Note: The transition box should enclose the refinement box. The size of the transition box determines how aggressive the transition will be. It is recommended that you limit the transition to 1 element connection 3 elements (1:3).
7. Click Review on the guide bar to preview the box.
8. Click the box, enter a refinement size in the microdialog, then click Refine.
   The size should be smaller than the initial mesh.
