。关于liner单元的设置问题 [复制链接]

我在做巷道支护层模拟的时候，用liner单元来模拟支护层，但是设置了liner后计算时出现：：+++ WARNING: axial dir. of cables and piles or normal dir. of liners and geogrids at hared node out of alignment by more than 30 degrees。不知道这个WARNING会不会对计算有影响？

参考：Advancing Lined Tunnel with Slip (using linerSELs)
; --- Add shotcrete
sel liner id=1 range cyl end1 0 0 0 end2 0 1.01 0 rad 1.0
; --- Specify symmetry conditions for nodes along the 3 symmetry planes
sel node local xdir 1 0 0 ydir 0 -1 0 range x -0.1 0.1
sel node fix lsys range x -0.1 0.1
sel node fix x yr zr range x -0.1 0.1

sel node fix x yr zr range z -0.1 0.1
sel node fix y xr zr range y -0.1 0.1

sel node local xdir 1 0 0 ydir 0 -1 0 range x -0.1 0.1 x坐标范围在-0.1到0.1内的结构单元局部坐标系的x正方向为全局坐标系x方向的正向，y正方向为全局坐标系的y的负向。
