曾攀《有限元分析及应用》这本书后例题4是用ansys6.1做的，是一个高压容器封头等温塑性成形过程的有限元分析，但是用ansys13做不出来，原代码本里已给出，不知道哪里出了问题，就是不收敛，[eimg]2013/1220/w373h1655950_1387524637_274.jpg请各位同学帮帮忙。 finish !finish the last case /clear,start !restart /PREP7 ET,1,VISCO106 ET,2,TARGE169 ET,3,CONTA171 KEYOPT,1,3,1 ! axial symmetry model !* !* material property 1 !* MP,EX,1,1.84e4 MP,PRXY,1,0.4 TB,MISO,1,0,7, TBPT,,0.005,92 TBPT,,0.02,140 TBPT,,0.06,194 TBPT,,0.19,274 TBPT,,0.5,366 TBPT,,1.0,451 TBPT,,2,556 !* !* material property 2 !* MP,MU,2,0.15 !* Geometry modeling blc4,0,0,1800,180 k,,1200,-800, k,,1200,0, k,,2000,0, k,,0,180, k,,1000,1180, k,,1000,1580, l,7,6 l,6,5 l,9,10 lfillt,5,6,400 LOCAL,11,1,0,1180,0, , , ,1,1, csys,11 l,8,9 csys,0 CSDELE, 11, lsel,s,line,,2 lsel,a,line,,4,7,1 lesize,all,,,4 lsel,s,line,,1 lsel,a,line,,3 lesize,all,,,30 lsel,s,line,,8 lsel,a,line,,9 lesize,all, , ,8, , , , ,1 allsel, aatt,1,,1 amesh,all r,1,,, R,2, , ,2, , , , lsel,s,line,,5,9,1 latt,2,2,2 lsel,s,line,,1,3,2 latt,2,2,3 lsel,a,line,,5,9,1 lmesh,all finish /solu nsel,s,loc,x,0 d,all, , , , , ,UX, , , , , allsel lsel,s,line,,5,6 lsel,a,line,,8 nsll,s d,all, all , , , , , , lsel,s,line,,7,9,2 nsll,s,1 d,all,uy , -1500, , , ,, , , , , allsel ANTYPE,0 NLGEOM,1 AUTOTS,1 DELTIM,0.5,0.05,1 TIME,25 CNVTOL,F, ,0.1,2, , OUTRES,ALL,5 LNSRCH,1 NEQIT,35 PRED,ON,,ON NCNV,0,0,0,0,0 Solve  1.jpg [ Last edited by yhp_1990 on 2013-12-20 at 15:31 ] |
