谁能解决一下 这里的 spacing 1   spacing 1是 怎么回事 还有就是 ratio 是增长速率 还是斜率,
 
Nodes
specifies the number of nodes along the edge.The number may be modified
using the up and down arrows or by entering a number in the field.
Mesh law
Allows you to select one of several bunching laws described in detail in Bunching Laws.
Spacing
specifies the spacing of the first node from the beginning of the edge (first
cell height).When an edge is selected,an arrow appears along the edge.
Spacing 1 refers to the parameters
at the beginning end of the arrow,and Spacing
2 refers to the edge end where the arrow is pointing,as shown
in Figure 78.You may modify
the values of the parameters available for the selected Meshing law.The actual
values will differ from the requested values only if the requested values cannot
be met.For example,if the Edge length is 10 units,and you specify an initial
spacing of 6 on both sides and 11 nodes along the edge,the system will simply
space the nodes evenly,giving an initial spacing of 1 and a spacing ratio of
1.
Ratio
is the growth rate from one cell height to the next.Ratio 1 refers to the parameters at the beginning
end of the arrow,and Ratio 2
refers to the edge end where the arrow is pointing,as shown in the figure
below.

你选择一个edge后那个edge上不是有个箭头吗,靠近箭头,顺着箭头方向的那个端点就是spacing1的起点,另外一个就是spacing2的起点了,ratio是生长率,也就是你网格节点由密变疏的快慢.
