About the Limit Element in Mesh Morphing

Not all limit elements are allowed.

The limit element or its projection on the mesh according to projection type must lie completely on the mesh, for example the following cases are not allowed.

If the limit element does not lie on the mesh to deform, it is projected on the mesh to deform according to the projection type.

The limit element is not necessarily closed. An open limit element (pink curves in the following figures) which cuts the mesh into two areas is allowed. But the target element (white curve and points), once projected, must lie entirely inside one area.



The following cases are not allowed:

• The target element does not lie within one area.
  
  
  
  
• The limit element does not define areas:
  
  
• The limit element lies on several zones:
  
  
  Note: This can be solved using the Mesh Preparation in Digitized Shape Preparation.

Do not select a limit element if you do not need to limit the morphing.

Without a limit element:

• The boundary of the mesh to deform acts as the limit element.
• If the mesh to deform has several boundaries, the longest boundary is used as the limit element.
• If the mesh to deform does not have any boundary (closed volume mesh), an error message is displayed and you are requested to select a limit element.
