三种建立inter205 cohesive单元的方法
今天同sh_lin30版主一起学习了一下inter205,后处理中etable对该单元的使用.通过两个命令流建立cohesive单元,但是inter205单元的单元坐标系如何判断,同时如何判定结果的正确与否,仍然值得我等去思考.
第一种直接建模的方法就是使用e单元直接连接.
命令流如下:
/prep7
et,1,45
et,2,inter205
mp,ex,1,2e11
block,0,1,0,1,0,1.5
block,0,1,0,1,1.5,3
lesize,all,0.5
vmesh,all
nsel,s,loc,z,1.5
et,2,inter205
tb,czm,2,,,EXPO
TBDATA,1,2e8,1,1
type,2
mat,2
e,15,17,18,16,37,39,45,41
e,17,10,12,18,39,38,44,45
e,18,12,11,14,45,44,42,43
e,16,18,14,13,41,45,43,40
/solu
nsel,s,loc,z,3
f,all,fx,100e3
f,all,fz,-100e3
allsel
nsel,s,loc,z,0
d,all,all
allsel
solve
/post1
ETABLE,ssx,ss,X
ETABLE,ssxy,ss,Xy
ETABLE,ssxz,ss,Xz
ETABLE,sdx,sd,X
第二种直接建模的方法就是使用czmesh命令自动生成.
/prep7
et,1,45
et,2,inter205
mp,ex,1,2e11
block,0,1,0,1,0,1.5
block,0,1,0,1,1.5,3
local,11,1,0,0,0
esys,11
lesize,all,0.5
vmesh,all
et,2,inter205
tb,czm,2,,,EXPO
TBDATA,1,2e8,1,1
type,2
mat,2
nummrg,all
czmesh,,,1,z,1.5,
/solu
下面加载等同上面例子.
如何解决inter205单元的局部坐标呢?因为她直接影响着结果的对错啊.

感谢sh_lin30的关注,我把czmesh单元中使用单元组元的命令流给发出来吧,大家一起学习,这方法当作第三种吧
/prep7
et,1,45
et,2,inter205
mp,ex,1,2e11
block,0,1,0,1,0,1.5
block,0,1,0,1,1.5,3
local,11,1,0,0,0
esys,11
lesize,all,0.5
vmesh,all
et,2,inter205
tb,czm,2,,,EXPO
TBDATA,1,2e8,1,1
type,2
mat,2
nummrg,all
nsel,s,loc,z,1.0,1.5
esln,s,1
cm,e1,elem
nsel,s,loc,z,1.5,2.0
esln,s,1
cm,e2,elem
czmesh,e1,e2
后面的命令同上面两个例子.
本来想贴个图的,但不知道怎么贴,以后会再贴吧.
加油!
