constrains:creat by set?

rush021

在做约束的时候将需要约束的节点放到了一个set里面，然后用set建立约束，在计算时报错：
*** ERROR # 1000 in the input data:
Incorrect data in field # 3.
   Detected while reading line 18796 from file E:/xmd/Lx/6/123.fem:
  "SPC            6       0  1234560.0"

This line was interpreted as:
18796:SPC, 6, 0, 123456, 0.0
  Expected INT > 0, found  INTEGER (0).
Syntax error(s) found in bulk data 'SPC' card.

load types是SPC，set的card是SET_GRID。将SET取消，把约束建立在相应的节点上，错误消失，没整明白是什么原因，请各位指教，谢过！

(1)	(2)	(3)	(4)	(5)	(6)	(7)	(8)	(9)	(10)
SPC	SID 6	G 0	C 123456	D 0	G	C	D

看spc的格式，SPC, 6, 0, 123456, 0.0
当然报错
各位一定要学会看help

Field	Contents
SID	Identification number of single-point constraint set. (Integer > 0)
G	Grid or scalar point identification number. (Integer > 0)
C	Component numbers. (Integer zero or blank for scalar points, or up to six unique digits (0 < digit < 6) may be placed in the field with no embedded blanks for grid points.  The components refer to the coordinate system referenced by the grid points.)
D	Value of enforced displacement for all coordinates designated by G and C. (Real)

是的，谢谢答复
但是这是什么问题呢？
我想问的是，为什么把node 放到 SET里面,再用SET来建立约束时就出现这个问题？而单独用节点来约束，不用set时，就不会出现上述问题呢？
load types是SPC，set的card是SET_GRID,  radioss   bulkdata求解器

问题已经解决，谢谢版主的帮助！
由SET施加约束，出现的上面问题。
