【求助】施加的load没有显示
verify_7.5例子A.4在点3、8 施加 force 1, 在点5施加force 2
loadplot只显示了force 2, 没有显示force 1.
怎么回事呢?
另外下一段命令流看不懂
dof-system points
1 1 to 3 1
4 2 to 5 2
6 3 to 8 3
(说明:已经定义了三个skewsystem 1,2,3, 运行上一段命令把point 1 2 3 指为skewsystem 1, point 4 5 指为 skewsystem 2, point 6 7 8指为 skewsystem 3.)

dof-system points 这一段的increment按照你说的分别是1,2,3着就看不懂了。
比如: 6 3 to 8 3
从point6开始,increment为3,增加到point8 ,怎么会把point7也包括进来呢
