Updated smooth operator description
Smooth operator
~~~~~~~~~~~~~~~
-The Smooth operator smooths a mesh to improve areas plagued by jagged edges or sharp peaks.
+The Smooth Operator applies Laplacian Smoothing to a mesh, making the cells
+better shaped and the nodes more evenly distributed, which results in smoother
+edges and peaks throughout the mesh. Each node is moved
+towards a coordinate that is the average of its connected nodes. The
+**relaxation factor** determines how far along that path to move the node. A
+sweep over all nodes is a single iteration.

-The Smooth operator has a number of controls that can be used to tune mesh
-smoothness. One such control is the number of iterations, which controls the
-number of times the mesh relaxation algorithm is applied to the input mesh.
-Larger numbers of iterations will produce smoother meshes but will also take
-more time to compute. To change the number of iterations, type a new integer
-value into the **Maximum number of iterations** text field in the
-**Smooth attributes window** (see :numref:`Figure %s <smoothwindow>`).
-The relaxation factor is a floating point number in the range [0,1] and it
-controls how much the mesh is relaxed. Values near 1 produce a mesh that is
-very smooth relative to the input mesh. To use a new relaxation factor, type a
-floating point number into the **Relaxation Factor** text field. The
-**Maintain Features** check box allows you to tell VisIt to preserve sharp
-peaks in the mesh while still smoothing out most of the mesh. The angle in the
-**Feature Angle** text field determines which features are kept. Any mesh
-angles less than the feature angle are preserved while others are smoothed.
