NGEN, ITIME, INC, NODE1, NODE2, NINC, DX, DY, DZ, SPACE

Generates additional nodes from a pattern of nodes.
一个节点复制命令,它是将一组节点在现有坐标系统下复制到其它位置。

ITIME, INC
Do this generation operation a total of ITIME times, incrementing all nodes in the given pattern by INC each time after the first. ITIME must be > 1 for generation to occur.
ITIME: 复制的次数,包含自己本身。
INC: 每次复制节点时节点号码的增加量。例如,复制3、4、5、6的节点,INC设为10,则复制后的节点编号为13、14、15、16。

NODE1, NODE2, NINC
Generate nodes from the pattern of nodes beginning with NODE1 to NODE2 (defaults to NODE1) in steps of NINC (defaults to 1). If NODE1 = ALL, NODE2 and NINC are ignored and the pattern is all selected nodes [NSEL]. If NODE1 = P, graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI). A component name may also be substituted for NODE1 (NODE2 and NINC are ignored).
NODE1,NODE2,NINC: 选取要复制的节点,即要对哪些节点进行复制。从NODE1到NODE2,增量为NINC的节点会被选中。例如:3,9,2,则选中的是3、5、7、9。如果NODE1=ALL,NODE2和NINC会被忽略,所有的可选择节点都会被选取[见NSEL]。如果NODE1=P,则为屏幕操作选取。组的名称也替换为NODE1。

DX, DY, DZ
Node location increments in the active coordinate system (DR, Dθ, DZ for cylindrical, DR, Dθ, DΦ for spherical or toroidal).
每次复制时在当前坐标系统下,几何位置的改变量(对柱坐标系统为半径、角度θ和高度,对球坐标系统为半径、角度θ和角度Φ)。

SPACE
Spacing ratio. Ratio of last division size to first division size. If > 1.0, divisions increase. If < 1.0, divisions decrease. Ratio defaults to 1.0 (uniform spacing).
间距比,是最后一个尺寸和第一个尺寸的比值。如果大于1,尺寸增加。如果小于1,尺寸减小。默认为1。

Note
The average spacing ratio remains 1.0, such that the location of the last generated set will be the same regardless of SPACE. SPACE only serves to skew the position of the nodes between the pattern set and the last set.
若平均间距比保持为1,则不管间距比为多少,最后的节点集位置相同。间距比只用于倾斜选择节点和最后生成节点之间的位置。

Notes
Generates additional nodes from a given node pattern. Generation is done in the active coordinate system. Nodes in the pattern may have been generated in any coordinate system.
从已知节点集合中复制节点。复制时在当前坐标系统下完成的。集合中的节点可以在仍和坐标系统下复制。

例:
NGEN,10,6,15,16,1,10
复制15~16的节点,数量为10个,代码增量为6,位移增量为x=10
复制结果是沿X方向阵列(包括1516共有10组),阵列后的节点编码为2122,27~28,……
