Smoothing Face Boundaries

You can improve the quality of faces by smoothing their boundaries.

Before you begin:
  • It is impossible to process a boundary limiting a face stretching over a grid of patches.
  • The links between neighbor faces are not taken into account. So be careful not to increase existing gaps or not to create new ones.
  • It is impossible to process only a portion of a boundary.
  • The maximum deformation distance allowed is 0.001.

  1. Check the number of edges composing the boundary of the surface you want to process.
    1. Select the surface.
    2. From the Prepare section, click Boundary .
    3. Click OK.
      A boundary is created.
    4. From the Prepare section, click Disassemble and select the boundary you have created.
      Now All Cells indicate the number of edges making the boundary.
    5. Delete the boundary as you no longer need it.
  2. From the Geometry section, click Face Smooth .
  3. Select a surface.
  4. Define a correction level for Distance, Tangency, or Curvature.
  5. Select required check boxes to delete short curves or reduce the number of edges.
  6. Check the result under Visualization.
  7. Click OK to reduce the number of edges.
    The input surface is sent to the NoShow, a new smoothed surface has been created.
  8. Repeat Step 1 on this new surface. The new boundary is made of fewer curves.
  9. Repeat Face Smooth on smoothed faces as required.

If the face can be smoothed:

  • After the first Apply, the input faces are sent to the No Show, and are replaced by the smoothed faces, that are automatically selected for another Apply with other values, if need be. Their name is suffixed with _smoothed. The new gap values are also displayed in green.
  • If you click Apply again, the first smoothed faces are sent to the No Show, the name of the face is suffixed with _smoothed and the iteration rank.
  • If the face cannot be smoothed or if the deformation exceeds the gaps authorized, the information appears in red, with the reason of the failure.
