In a sequential thermal - structural (ETCHG,TTS) analysis, can I add structural elements after using LDREAD to apply the temperatures from the thermal analysis?
Yes, the following example demonstrates: !***** First perform thermal analysis fini /clear /filn,thermal_structural /view,1,.5,1,.5 /eshape,1 /prep7 mp,ex,1,30e6 !Material Properties mp,nuxy,1,0.3 mp,alpx,1,9.8e-06 mp,kxx,1,0.025 mp,c,1,0.28 mp,dens,1,0.054 et,1,solid90 !Thermal Solid Element blc4,0,0,10,10,10 esiz,2 vmesh,1 asel,s,area,,1,5,1 sfa,all,,conv,0.014,100 !Apply Convection alls asel,s,area,,6 nsla,s,1 d,all,temp,50 !Apply Temperatures alls /solu solve !Solve thermal analysis to produce *.rth file !***** Now perform structural analysis /prep7 etch,tts !Change to compatible Stuctural element, SOLID95 !*** Use LDREAD to apply temperatures from thermal analysis *** !*** as Body Force temperatures in structural analysis *** ldread,temp,,,,,thermal_structural,rth et,2,beam188 !Add new structural elements sectype,1,beam,I,,0 secdata,0.5,0.5,0.5,0.1,0.1,0.1 type,2 n,1000,5,5,20 e,1000,node(0,0,10) e,1000,node(10,0,10) e,1000,node(0,10,10) e,1000,node(10,10,10) eplo d,1000,all !Fix end of beams /solu solve !Solve structural analysis /post1 plns,u,sum !Plot displacements |
