Smoothing is used to adjust the locations of element

To apply smoothing to the elements of your mesh:
- -- -
1. Display a mesh or a submesh in the 3D - viewer.
- -2. In the Modification
- menu select the Smoothing item
- or click 
button in the toolbar. The dialog
- box contains the following fields which should be specified:
- -
Id Elements field allows to specify - the elements which should be smoothed by selecting them in the 3D viewer - (lock Shift button to select several - elements).
Select whole mesh, - submesh or group - smoothing is applied - to the whole mesh or its part.
Fixed nodes - ids: some nodes keep their location during smoothing. If a mesh - is built on a geometry shape, the nodes built on geometrical edges are - always fixed. If smoothing is applied to a part of a mesh then the boundary - nodes of an elements set are also fixed. Any other nodes may be additionally - fixed.
Smoothing - Method:
Laplacian - smoothing pulls a node toward the center of surrounding nodes directly - connected to that node along an element edge. Centroidal smoothing pulls - a node toward the element-area-weighted centroid of the surrounding elements. - Typically, the Laplacian method will produce the mesh with the least element - distortion. It is also the faster method.
Centroidal - smoothing usually produces a mesh that has more uniform element sizes. - Both methods produce good results with "free" meshes.
- -
Iteration limit: both of the smoothing - methods use an iterative procedure to converge toward a smoothed mesh. - All nodes are smoothed according to one of the techniques shown above. - Then the smoothing is reevaluated with the updated nodal locations. This - process continues until the maximum number of iterations has been exceeded, - or all elements has aspect ratio less or equal than the specified one.
Max. aspect ratio.

3. Click the Apply - or OK button to confirm - the operation.
