使用生死单元的喷涂模拟中死单元的数值为什么会变化呢？
|
|
做的等离子喷涂模拟，三种材料，各自赋有初始温度条件，我时间步按照1s设置，感觉不收敛，我就给了一个初始的0.001s，但是我用生死单元的时候，就会出现，还没激活的死单元的温度条件发生了变化。求大家帮忙看下，是哪里出现的问题。 /PREP7 !* ET,1,PLANE13 !* KEYOPT,1,1,4 KEYOPT,1,2,0 KEYOPT,1,3,1 KEYOPT,1,4,0 KEYOPT,1,5,0 !* MP,DENS,1,2715 MP,KXX,1,221.5 MP,C,1,921 MP,EX,1,0.689E11 MP,PRXY,1,0.33 MP,ALPX,1,23.6E-6 MP,DENS,2,7320 MP,KXX,2,4.3 MP,C,2,501 MP,EX,2,2.25E11 MP,PRXY,2,0.30 MP,ALPX,2,14E-6 MP,DENS,3,6037 MP,KXX,3,1.5 MP,C,3,500 MP,EX,3,0.53E11 MP,PRXY,3,0.25 MP,ALPX,3,7.2E-6 *SET,Sub_length,0.025 *SET,Sub_height,0.002 *SET,Coat_height,0.0005 *SET,Metallic_height,0.0001 *SET,YSZ_height, Coat_height- Metallic_height *SET,Coat_layer,10 *SET,Sub_layer,5 *SET,Single_height, Coat_height /Coat_layer *SET,Ta,300 *SET,Ha,8 *SET,Tg_metallic,723 *SET,Tg_YSZ,748 *SET,Hg,320 *SET,dt,1e-7 *SET,Inittemp_sub,300 *SET,Inittemp_metallic,1673 *SET,Inittemp_YSZ,2478 *SET,Single_time,10 K,1,0,0 K,2,25e-3,0 K,3,25e-3,2e-3 K,4,0,2e-3 K,5,0,2.1e-3 K,6,25e-3,2.1e-3 K,7,25e-3,2.5e-3 K,8,0,2.5e-3 A,1,2,3,4 A,3,4,5,6 A,5,6,7,8 Aglue,all Numcmp,all /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST APLOT /PNUM,KP,0 /PNUM,LINE,0 /PNUM,AREA,1 /PNUM,VOLU,0 /PNUM,NODE,0 /PNUM,TABN,0 /PNUM,SVAL,0 /PNUM,DOMA,0 /NUMBER,0 !* /PNUM,ELEM,0 /REPLOT !* /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST /DIST,1,0.924021086472,1 /REP,FAST FINISH /SOL FINISH /PREP7 CM,_Y,AREA ASEL, , , , 1 CM,_Y1,AREA CMSEL,S,_Y !* CMSEL,S,_Y1 AATT, 1, , 1, 0, CMSEL,S,_Y CMDELE,_Y CMDELE,_Y1 !* CM,_Y,AREA ASEL, , , , 2 CM,_Y1,AREA CMSEL,S,_Y !* CMSEL,S,_Y1 AATT, 2, , 1, 0, CMSEL,S,_Y CMDELE,_Y CMDELE,_Y1 !* CM,_Y,AREA ASEL, , , , 3 CM,_Y1,AREA CMSEL,S,_Y !* CMSEL,S,_Y1 AATT, 3, , 1, 0, CMSEL,S,_Y CMDELE,_Y CMDELE,_Y1 !* LESIZE,1,,,250 LESIZE,3,,,250 LESIZE,6,,,250 LESIZE,9,,,250 LESIZE,2,,,5 LESIZE,4,,,5 LESIZE,7,,,2 LESIZE,5,,,2 LESIZE,8,,,8 LESIZE,10,,,8 MSHAPE,0,2D MSHKEY,1 !* FLST,5,3,5,ORDE,2 FITEM,5,1 FITEM,5,-3 CM,_Y,AREA ASEL, , , ,P51X CM,_Y1,AREA CHKMSH,'AREA' CMSEL,S,_Y !* AMESH,_Y1 !* CMDELE,_Y CMDELE,_Y1 CMDELE,_Y2 !* /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST /FOC,1,-0.3,,,1 /REP,FAST NSEL,S,LOC,Y,0 SF,ALL,CONV,Ha,Ta ALLSEL,ALL NSEL,S,LOC,Y,0,Sub_height IC,ALL,TEMP, Inittemp_sub ALLSEL,ALL NSEL,S,LOC,Y,Sub_height+dt,Sub_height+Metallic_height IC,ALL,TEMP, Inittemp_metallic ALLSEL,ALL NSEL,S,LOC,Y,Sub_height+ Metallic_height+dt,Sub_height+Coat_height IC,ALL,TEMP, Inittemp_YSZ ALLSEL,ALL FINISH /SOLU !* ANTYPE,4 !* TRNOPT,FULL LUMPM,0 !* NSUBST,500,1000,200 OUTRES,ERASE OUTRES,ALL,50 NSEL,S,LOC,Y, Sub_height, Sub_height +Coat_height ESLN,S,1 EKILL,ALL ESEL,S,LIVE EPLOT *DO,i, 1,Coat_layer,1 TIME,Single_time*(i-1)+0.001 NSEL,S,LOC,Y, Sub_height+Single_height*(i-1),Sub_height +Single_height*i ESLN,S,1 EALIVE,ALL ALLSEL,ALL NSEL,S,LOC,Y, Sub_height +Single_height*i SF,ALL,CONV,Hg,Tg_metallic ALLSEL,ALL NSEL,S,LOC,Y, Sub_height +Single_height*(i-1) SFDELE,ALL,CONV ALLSEL,ALL SOLVE TIME,Single_time*i SOLVE ESEL,S,LIVE EPLOT *ENDDO ESEL,S,LIVE EPLOT FINISH |
