Use the Edit Elements: Smooth tool
to optimize the quality of selected elements.
A node of a shell element is free, and therefore can be moved, if none of the
following statements are true:
It is used by an element that was not selected.
It is selected as an anchor node.
It is attached to an edge, vertex, or meshing fixed point of a surface.
It is used by a 1D element (whether or not that element is selected).
It is not attached to a surface, but is on a feature line of the mesh of the
selected plate or shell elements.
From the Elements ribbon, click the Edit Elements > Smooth tool.
Figure 1.
Elements are colored according to how
well they adhere to the pre-set quality requirements defined in the criteria
file.
Optional: On the guide bar, click to to define the options used to
edit elements.
Select the element(s) to smooth.
Optional: Select anchor nodes in the following ways:
Hold Ctrl while left-clicking.
Activate the Anchors selector on the guide bar then make your selection.
In the microdialog, select a smoothing method then
click Smooth.

Calculates the lengths of all of the elements’ edges to finds the
extreme values. If the ratio of smallest to largest is below a
certain threshold, than the Fix Shape method will be used. If the
ratio of smallest to largest is above a certain threshold, than the
Fix Size method will be used.
Fix Size
Moderates variations in element edge size through the mesh using a
modified Laplacian over-relaxation that correctly handles a mixture
of quad and tria elements.
Fix Shape
Moderates variations in element aspect ratio through the mesh using
a modified isoparametric-centroidal over-relaxation that correctly
handles a mixtures of quad and tria elements.
