求助：关于径向载荷
<P>想在A3面上按柱坐标的x向加径向位移,下面是我的命令流,我对这部分不懂,错误很多,麻烦会做的帮忙改一下,谢谢了<BR>/prep7<BR>/units,si<BR>cylind,0.45,0.5,0,0.5,30,60<BR>et,1,solid45<BR>mp,ex,1,2.1e11<BR>mp,nuxy,1,0.3<BR>esize,0.05<BR>vsweep,1<BR>cs,11,1<BR><BR><BR>asel,s,,,3 <BR>nsla,s,1<BR>nsel<BR>nrotat<BR>cm,jiechu1,node<BR><BR><BR>/solu<BR>cmsel,s,jiechu1<BR>d,all,ux,0.2<BR>d,all,uy,0<BR><BR>asel,all<BR>asel,s,,,2 <BR>nsla,s,1<BR>d,all,uz,0<BR>asel,s,,,1<BR>nsla,s,1<BR>d,all,uz,0<BR><BR>allsel,all<BR>time,2<BR>nsubst,10<BR>autots,on<BR>nropt,full,,off<BR>nropt,unsym,,off<BR>neqit<BR>lnsrch,auto<BR>nlgeom,on<BR>ncnv,0,0,0,0,0 <BR>solve </P>回复：（forseti）求助：关于径向载荷
