请问：为何表面单元上添加的热对流不起作用，命令流如下
fini/clear
/prep7
et,1,plane55 !定义单元类型
ET,4,SOLID5 !选择单元类型(硅片，玻璃盘)
ET,5,Surf152
MP,KXX,1,2.22 ! 定义材料热性能参数 1～冰，2～硅，3～石英玻璃
MP,DENS,1,920
MPTEMP,1,-10,-1,0,10
MPDATA,ENTH,1,1,0,3.78E7,7.98E7,1.22E8
mp,kzz,4,1e9 !W/m-K !转换材料
mp,kyy,4,1e9 !W/m-K
mp,kxx,4,1e9 !W/m-K
MP,c,4,1e-2
mp,dens,4,1e-9
MP,ENTH,4,1 !J/m^3
/view,1,1,1,1
cylind,0,0.09,0,0.03,0,360
asel,s,,,2 !选择圆柱源面并给圆柱源面分配属性
aatt,1,1,1
save
lsel,s,,,5,8,,0 !划分源面上的线
lesize,all,,,5
amesh,2 !划分圆柱的源面
lsel,s,loc,z,0.015 !给厚度z方向上的线指定单元尺寸
lesize,all,0.005,,,,,,,1
vsel,s,,,1
vatt,1,,4 !材料1，单元4
vsweep,1,2,,1 !对圆柱进行扫掠
allsel,all
esel,s,type,,1
aclear,all
ALLSEL,ALL
EPLOT
FINISH
/solu
antype,trans
bfunif,temp,-10
Antype,4
Trnopt,full
Autots,on
tintp
Lnsrch,on
ASEL,S,,,2
type,5 !定义属性
NSLA,S,1
ESLN,S,0
ESURF
esel,r,type,,5
!sfe,all,1,hflux,,20正确
SFE,ALL,1,CONV,,23.2
SFE,ALL,1,CONV,2,10000 !表面效应单元施加对流系数
allsel,all
nsel,s,loc,z,0.026,0.03
ESLN,S,0
esel,r,type,,4
Sfe,all,1,hflux,,200
allsel
Time,240
Nsubst,10
SOLVE SFE,ALL,1,CONV,,23.2
SFE,ALL,1,CONV,2,10000
好像应该是SFE,ALL,1,,CONV,,23.2
SFE,ALL,1,,CONV,2,10000
你可以试试
我没有用过表面效应单元 已经解决，是keyopt没有定义
