In this step, the node spacing on the end of your selected Target Edge(s) will be modified to match the node spacing on the selected Reference Edge. A better quality mesh is achieved by smoothing the size change between adjacent cells.
> Pre-Mesh Params 
> Match Edges 
Match the edge spacing manually.
Retain Selected in the Method drop-down list.
For Reference Edge, click
(Select edge(s)) and then select edge 42–43.For Target Edge(s), click
(Select edge(s)) and then select edges 41–42 and 42–33. Click the middle-mouse button to accept the selection.Click .
Enable .
> The Mesh dialog box will appear, asking if you want to recompute the mesh. Click Yes.
Match the edge spacing automatically.
Select Automatic from the Method drop-down list.
Ensure that the Spacing is set to Minimum.
Click
(Select vert(s) ) and then 
(Select all appropriate visible objects) from the Select Blocking-vertex toolbar.Alternatively, with the mouse in the display window, you can enter
vfor all visible vertices, or drag a box to select all vertices.For Ref. Edges, click
(Select edge(s)) and then select the edges 13-34 and 34-42. Click the middle-mouse button to accept the selection.This selection chooses the i and j index at each vertex for matching.
Click .
Disable and then enable Pre-Mesh to recompute the mesh.
