ANSYS热分析过程中，rth文件没保存，以致温度应力分析做不出来，请问该如何设置？ 已有1人参与

写的命令流如下 在求解出温度分布之后，求解温度应力时，提示：rth文件没有，请问如何生成呢 命令流如下： finish /clear /filname,s /title, temperature analysis !c35砼物理参数 u=0.15 !泊松比 alpx=1e-5 !热膨胀系数,1/oC kxx=2.49 !导热系数,W/m.oC dens=2420 !密度,kg/m3 c=0.980 !比热,J/Kg.oC cc=959.08 !对流系数kJ/m3. 侧面 cf=369.4 !对流系数kJ/m3. 顶面 tt=21.2 !浇筑/入模温度oC te=18 !环境温度oC !c20砼垫层物理参数 u2=0.2 !泊松比 alpx2=1e-5 !热膨胀系数,1/oC kxx2=65.28 !导热系数,W/m.oC dens2=2400 !密度,kg/m3 c2=0.920 !比热,J/Kg.oC tt2=15 !地基温度oC /prep7 ET,1,SOLID70 !c20砼 基础 MP,ALPX,1,alpx2 MP,KXX,1,kxx2 MP,DENS,1,dens2 MP,C,1,c2 !c35砼材料特性2~4号 MP,ALPX,2,alpx MP,KXX,2,kxx !定义上面层2.7材料属性编号2 MP,DENS,2,dens MP,C,2,c MP,ALPX,3,alpx MP,KXX,3,kxx !定义上面层2.7材料属性编号3 MP,DENS,3,dens MP,C,3,c MP,ALPX,4,alpx MP,KXX,4,kxx !定义上面层2.6材料属性编号4 MP,DENS,4,dens MP,C,4,c block,-41.85,-11.85,-11.75,11.75,-1,8 block,11.85,41.85,-11.75,11.75,-1,8 k,17,-11.85,-7.5,-1 k,18,-11.85,-7.5,8 k,19,-11.85,7.5,-1 k,20,-11.85,7.5,8 k,21,-9.35,-5,-1 k,22,-9.35,-5,8 k,23,-9.35,5,-1 k,24,-9.35,5,8 a,17,18,20,19 a,19,20,24,23 a,21,22,24,23 a,17,18,22,21 a,17,19,23,21 a,18,20,24,22 va,13,14,15,16,17,18 k,25,11.85,-7.5,-1 k,26,11.85,-7.5,8 k,27,11.85,7.5,-1 k,28,11.85,7.5,8 k,29,9.35,-5,-1 k,30,9.35,-5,8 k,31,9.35,5,-1 k,32,9.35,5,8 a,25,26,28,27 a,27,28,32,31 a,29,30,32,31 a,25,26,30,29 a,25,27,31,29 a,26,28,32,30 va,19,20,21,22,23,24 a,21,22,30,29 a,23,24,32,31 a,22,24,32,30 a,21,23,31,29 va,25,26,27,28,21,15 vglue,all vsbw,all wpoffs,,,2.7 vsbw,all wpoffs,,,2.7 vsbw,all wprota,,90 wpoffs,,,7.5 vsbw,all wpoffs,,,-15 vsbw,all wpcsys allsel lsel,s,loc,x,-41.85, lsel,a,loc,x,41.85 lsel,a,loc,x,11.85 lsel,a,loc,x,-11.85 lsel,r,loc,y,-11.74,-7.51 lesize,all,,,5 allsel lsel,s,loc,x,-41.85, lsel,a,loc,x,41.85 lsel,a,loc,x,11.85 lsel,a,loc,x,-11.85 lsel,r,loc,y,7.51,11.74 lesize,all,,,5 allsel lsel,s,loc,x,-41.85, lsel,a,loc,x,41.85 lsel,a,loc,x,11.85 lsel,a,loc,x,-11.85 lsel,r,loc,y,-7.49,7.49 lesize,all,,,20 allsel, lsel,s,loc,y,11.75, lsel,a,loc,y,-11.75 lsel,r,loc,x,-41.84,-11.86 lesize,all,,,30 allsel, lsel,s,loc,y,11.75, lsel,a,loc,y,-11.75 lsel,r,loc,x,11.86,41.84 lesize,all,,,30 allsel, lsel,s,loc,y,7.5, lsel,a,loc,y,-7.5 lsel,r,loc,x,11.86,41.84 lesize,all,,,30 allsel, lsel,s,loc,y,7.5, lsel,a,loc,y,-7.5 lsel,r,loc,x,-41.84,-11.86 lesize,all,,,30 allsel lsel,s,loc,x,-11.84,-9.36 lsel,a,loc,x,9.36,11.84 lesize,all,,,5 allsel lsel,s,loc,x,-9.34,9.34 lesize,all,,,20 allsel lsel,s,loc,x,-9.35 lsel,a,loc,x,9.35 lsel,r,loc,y,-4.99,4.99 lesize,all,,,20 allsel lsel,s,loc,x,-41.85 lsel,r,loc,y,-11.75 lesize,all,,,4 allsel lsel,s,loc,x,41.85 lsel,r,loc,y,11.75 lesize,all,,,4 allsel lsel,s,loc,x,-41.85 lsel,r,loc,y,11.75 lesize,all,,,4 allsel lsel,s,loc,x,41.85 lsel,r,loc,y,-11.75 lesize,all,,,4 allsel lsel,s,loc,x,-11.85 lsel,r,loc,y,-7.5 lesize,all,,,4 allsel lsel,s,loc,x,11.85 lsel,r,loc,y,-7.5 lesize,all,,,4 allsel lsel,s,loc,x,-11.85 lsel,r,loc,y,7.5 lesize,all,,,4 allsel lsel,s,loc,x,11.85 lsel,r,loc,y,7.5 lesize,all,,,4 allsel lsel,s,loc,x,-9.35 lsel,r,loc,y,-5 lesize,all,,,4 allsel lsel,s,loc,x,9.35 lsel,r,loc,y,5 lesize,all,,,4 allsel lsel,s,loc,x,-9.35 lsel,r,loc,y,5 lesize,all,,,4 allsel lsel,s,loc,x,9.35 lsel,r,loc,y,-5 lesize,all,,,4 allsel !垫层0.5 mshape,0 mshkey,1 vsel,s,loc,z,-0.51,0.01 vatt,1,1,1 vmesh,all allsel !2.7 mshape,0 mshkey,1 vsel,s,loc,z,-0.01,2.71 vatt,2,2,1 vmesh,all allsel !2.7 mshape,0 mshkey,1 vsel,s,loc,z,2.69,5.41 vatt,3,3,1 vmesh,all allsel !2.6 mshape,0 mshkey,1 vsel,s,loc,z,5.39,8.01 vatt,4,4,1 vmesh,all !输入热生成率函数 *SET,_FNCNAME,'heats' *DIM,%_FNCNAME%,TABLE,6,16,1 !
