beam188单元,第一张图是变截面正常的网格划分,后面的图是第41变截面与42变截面过渡处的网格,以下为部分代码:
!=======自定义截面
sectype,7,beam,mesh
secread,jm7,sect,,mesh
secoffset,user,0,0.54
sectype,8,beam,mesh
secread,jm8,sect,,mesh
secoffset,user,0,0.72
sectype,9,beam,mesh
secread,jm9,sect,,mesh
secoffset,user,0,0.93
!!=======变截面
sectype,40,taper
secdate,6,0,0,22.5
secdate,7,0,0,27
sectype,41,taper
secdate,7,0,0,27
secdate,8,0,0,31.5
sectype,42,taper
secdate,8,0,0,31.5
secdate,9,0,0,36
sectype,43,taper
secdate,9,0,0,36
secdate,10,0,0,40.5
!=======
k,7,0,0,27
k,8,0,0,31.5
k,9,0,0,36
K,50,0,10,0
l,7,8
l,8,9
lesize,all,,,10
lsel,s,,,7
latt,1,,1,,50,,41
lsel,s,,,8
latt,1,,1,,50,,42
lsel,all
lmesh,all
其他代码格式一样,但就只有这个部分存在这个问题。跪求各位大佬解答。
