Are there any ANSYS LS-DYNA full restart examples showing a change in
displacement loading via EDLOAD? I can get force loading to change,
but not displacement loading.

Please see the ANSYS LS-DYNA 9.0 model below. Be careful not to make any abrupt changes to displacements, as infinite accelerations will result. ! = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = fini /clear /title, ANSYS LS-DYNA 9.0 Full Restart Example /filnam,file_1 /plopts,info,1 /pnum,node,1 /pnum,elem,1 /view,,1,2,3 /prep7 et,1,SHELL163,10 r,1,,5,0.10 edint,5,4 mp,ex,1,30.0e6 mp,nuxy,1,0.30 mp,dens,1,0.00074 tb,biso,1 tbdata,1,60.0e3 tbdata,2,30.0e4 edmp,hgls,1,5 mat,1 type,1 real,1 n,1, 0.0, 0.0, 0.0 n,2, 1.0, 0.0, 0.0 ngen,4,2,1,2,1,0.0,1.0,0.0 e,1,2,4,3 e,3,4,6,5 e,5,6,8,7 eplot edpart,create eddamp,all,,0.02 eddamp,1,,1.0e-4 fini /solu nsel,s,loc,y,0.0 cm,nbase,node esln cm,ebase,elem nsel,s,loc,y,3.0 cm,ntip,node esln cm,etip,elem esel,all nsel,all eplot d,nbase,ux,0.0,,,,uy,uz,rotx,roty,rotz *dim,etime,,3 *dim,zdisp,,3 etime(1)=0.0,0.05,0.101 zdisp(1)=0.0,0.50,0.50 edload,add,uz,,ntip,etime(1),zdisp(1) time,0.100 edrst,20 edhtime,200 edhist,ntip edhist,nbase edhist,ebase edenergy,1,1,1,1 edout,glstat edout,spcforc edopt,add,,both save solve save fini /post1 file,file_1,rst set,last /edge,,1 /dscale,,1 plnsol,u,z,2 /wait,2 fini /post26 numvar,30 file,file_1,his nsol,2,8,u,z,n8uz prvar,2 plvar,2 /wait,2 fini ! = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = /solu edstart,3,,,d3dump01 ! full restart - Jobname changed automatically ... edis ! stress initialization for all parts ... *dim,etime2,,3 *dim,zdisp2,,3 etime2(1)=0.10,0.15,0.201 zdisp2(1)=0.50,1.00,0.75 edload,add,uz,,ntip,etime2(1),zdisp2(1) time,0.200 edrst,40 edhtime,400 edhist,ntip edhist,nbase edhist,ebase edenergy,1,1,1,1 edout,glstat edout,spcforc edopt,add,,both save solve save fini /post1 file,file_2,rst set,last /edge,,1 /dscale,,1 plnsol,u,z,2 /wait,2 fini /post26 numvar,30 file,file_2,his nsol,2,8,u,z,n8uz prvar,2 plvar,2 /eof . |
