定义了一组参数生成锚索，锚索应该是并列的一排，怎么成这样了，请大家帮我看看这个命令哪出错了。def material
;锚索长度
L1=32
L2=32
L3=27
;锚固段长度
L01=10
L02=10
L03=10
;锚索角度
θ1=20
θ2=25
θ2=30
;锚索起始端坐标值
x_01=1.5
x_02=1.5
x_03=1.5
y_01=81.5
y_02=81.5
y_03=81.5
z_01=-30
z_02=-29
z_03=-28
;锚固底端坐标值
x_11=1.5
x_12=1.5
x_13=1.5
y_11=y_01+L1*cos(θ1)
y_12=y_02+L2*cos(θ2)
y_13=y_03+L3*cos(θ3)
z_11=z_01+L1*sin(θ1)
z_12=z_02+L2*sin(θ2)
z_13=z_03+L3*sin(θ3)
;自由端与锚固段相接处坐标值
x_21=1.5
x_22=1.5
x_23=1.5
y_21=y_11-L01*cos(θ1)
y_22=y_12-L02*cos(θ2)
y_23=y_13-L03*cos(θ3)
z_21=z_11-L01*sin(θ1)
z_22=z_12-L02*sin(θ2)
z_23=z_13-L03*sin(θ3)
end
material
sel cable id 1 beg x_01 y_01 z_01 end x_21 y_21 z_21 nseg 22
sel cable id 1 beg x_21 y_21 z_21 end x_11 y_11 z_11 nseg 10
sel cable id 2 beg x_02 y_02 z_02 end x_22 y_22 z_22 nseg 22
sel cable id 2 beg x_22 y_22 z_22 end x_12 y_12 z_12 nseg 10
sel cable id 3 beg x_03 y_03 z_03 end x_23 y_23 z_23 nseg 17
sel cable id 3 beg x_23 y_23 z_23 end x_13 y_13 z_13 nseg 10
怎么回事啊，这是？
