This dialog handles localized mesh refinement along surfaces. The refinement procedure operates in two separate modes:

• refinement along stripped surfaces (typically engaged during shape optimization) and
• refinement along material-void boundaries (typically engaged during topology optimization).

To refine the mesh along surfaces ...

1. Select either the

• Refine along stripped surfaces or the
• Refine along material-void boundaries

2. Click the Analyze button in order to get the refine region mesh data, most importantly, maximal and average element edge lengths.

3. Examine carefully the reported maximal and average edge lengths; enter the refine parameters: edge subdivide threshold and refine region bandwidth. Edges exhibiting a length above the threshold will be subdivided.

4. Optionally, enter the maximal allowed model increase percentage (a value of zero means there is no limitation).

5. Click the Refine button.

IMPORTANT. Mesh refinement might result in slight redistribution of applied loads in some localized regions.

NOTE. All changes done within this dialog become permanent only after exiting the dialog. Before exit, all these changes can be reversed by choosing the Undo all changes command from the Additional menu.
