单道激光熔覆ansys程序求助。

紧急求助各位大侠：单道激光熔覆ansys程序如下，当扫描光束移动过后，前一点温度降不下来，反正有升高的趋势（理论上说前一点温度应该是降低的）。各位的不吝指教是我能否按时毕业的关键，跪求解答！  !**************temperature calculation**************** FINISH /CLEAR,START-- /CWD,F:\ansys_E_file /FILNAME,temperature,o /TITLE,Transient Analysis of Laser Prototype /UNITS,SI *SET,L3,0.3e-3 *SET,W3,0.3e-3 *SET,H3,0.15e-3 !---ALTERNATIVE PARAMETER-------------- *SET,L1,60*L3 *SET,W1,15*W3 *SET,H1,20*H3 *SET,L2,60*L3 *SET,W2,4*W3 *SET,H2,H3 /PREP7 ET,1,SOLID70 ET,2,SURF152 DOF,TEMP KEYOPT,2,4,1 KEYOPT,2,5,0 KEYOPT,2,7,0 KEYOPT,2,8,3 KEYOPT,2,11,0 MP,DENS,1,7840 MPTEMP,1,0,227,727,1727,2727 MPDATA,KXX,1,1,83.5,61.5,32.5,42.5,46.0 MPDATA,KYY,1,1,83.5,61.5,32.5,42.5,46.0 MPDATA,KZZ,1,1,83.5,61.5,32.5,42.5,46.0 MPDATA,C,1,1,430,540,980,847,400 MPDATA,HF,1,1,160.5,425.2,1298.1,3962.4,7616.4 MPTEMP,1,0,1533,1595,1670 MPDATA,ENTH,1,1,0,7.5E9,9.6E9,1.05E10 TOFFST,273 !Modeling BLC4,0,0,L1,W2,-H1 BLC4,0,W2,L1,W1-W2,-H1 BLC4,0,0,L1,W2,H2 VSEL,ALL VGLUE,ALL ALLSEL,ALL Mshape,0,3d TYPE,1 LSEL,S,LENGTH,,L1,,,0 LESIZE,ALL,L3,,,,0,,,0 LSEL,S,LENGTH,,W2,,,0 LESIZE,ALL,W3,,,,0,,,0 LSEL,S,LENGTH,,H2,,,0 LESIZE,ALL,H3,,,,0,,,0 LSEL,S,LENGTH,,W1-W2,,,0 LESIZE,ALL,W3,,,,0,,,0 LSEL,S,LENGTH,,H1,,,0 LESIZE,ALL,H3,,,,0,,,0 VMESH,ALL ALLSEL,ALL ASEL,S,AREA,,14,21,7 ASEL,A,AREA,,24 Mshape,0,2d TYPE,2 LSEL,S,LENGTH,,L1,,,0 LESIZE,ALL,L3,,,,0,,,0 LSEL,S,LENGTH,,W2,,,0 LESIZE,ALL,W3,,,,0,,,0 LSEL,S,LENGTH,,W1-W2,,,0 LESIZE,ALL,W3,,,,0,,,0 LSEL,S,LENGTH,,H2,,,0 LESIZE,ALL,H3,,,,0,,,0 AMESH,ALL ALLSEL,ALL /VIEW,1,-0.35,-0.88,0.35 /ANGLE,1,45 /REPLOT,FAST !**************temperature calculation**************** FINISH /CLEAR,START-- /CWD,F:\ansys_E_file /FILNAME,temperature,o /TITLE,Transient Analysis of Laser Prototype /UNITS,SI *SET,L3,0.3e-3 *SET,W3,0.3e-3 *SET,H3,0.15e-3 !---ALTERNATIVE PARAMETER-------------- *SET,L1,60*L3 *SET,W1,15*W3 *SET,H1,20*H3 *SET,L2,60*L3 *SET,W2,4*W3 *SET,H2,H3 /PREP7 ET,1,SOLID70 ET,2,SURF152 DOF,TEMP KEYOPT,2,4,1 KEYOPT,2,5,0 KEYOPT,2,7,0 KEYOPT,2,8,3 KEYOPT,2,11,0 MP,DENS,1,7840 MPTEMP,1,0,227,727,1727,2727 MPDATA,KXX,1,1,83.5,61.5,32.5,42.5,46.0 MPDATA,KYY,1,1,83.5,61.5,32.5,42.5,46.0 MPDATA,KZZ,1,1,83.5,61.5,32.5,42.5,46.0 MPDATA,C,1,1,430,540,980,847,400 MPDATA,HF,1,1,160.5,425.2,1298.1,3962.4,7616.4 MPTEMP,1,0,1533,1595,1670 MPDATA,ENTH,1,1,0,7.5E9,9.6E9,1.05E10 TOFFST,273 !Modeling BLC4,0,0,L1,W2,-H1 BLC4,0,W2,L1,W1-W2,-H1 BLC4,0,0,L1,W2,H2 VSEL,ALL VGLUE,ALL ALLSEL,ALL Mshape,0,3d TYPE,1 LSEL,S,LENGTH,,L1,,,0 LESIZE,ALL,L3,,,,0,,,0 LSEL,S,LENGTH,,W2,,,0 LESIZE,ALL,W3,,,,0,,,0 LSEL,S,LENGTH,,H2,,,0 LESIZE,ALL,H3,,,,0,,,0 LSEL,S,LENGTH,,W1-W2,,,0 LESIZE,ALL,W3,,,,0,,,0 LSEL,S,LENGTH,,H1,,,0 LESIZE,ALL,H3,,,,0,,,0 VMESH,ALL ALLSEL,ALL ASEL,S,AREA,,14,21,7 ASEL,A,AREA,,24 Mshape,0,2d TYPE,2 LSEL,S,LENGTH,,L1,,,0 LESIZE,ALL,L3,,,,0,,,0 LSEL,S,LENGTH,,W2,,,0 LESIZE,ALL,W3,,,,0,,,0 LSEL,S,LENGTH,,W1-W2,,,0 LESIZE,ALL,W3,,,,0,,,0 LSEL,S,LENGTH,,H2,,,0 LESIZE,ALL,H3,,,,0,,,0 AMESH,ALL ALLSEL,ALL /VIEW,1,-0.35,-0.88,0.35 /ANGLE,1,45 /REPLOT,FAST |
