多謝，這個(gè)問(wèn)題解決了。但是又出問(wèn)題了 Temperatures for material properties must be in ascending order. The MPTEMP command is ignored. 我把命令流改為這樣了 mptemp,,,,,,,, mptemp,1,25 mptemp,2,250 mptemp,3,500 mptemp,4,750 mptemp,5,1000 mptemp,6,1500 mptemp,7,1700 mptemp,8,2500 mpdata,kxx,1,,50 mpdata,kxx,1,,47 mpdata,kxx,1,,40 mpdata,kxx,1,,27 mpdata,kxx,1,,30 mpdata,kxx,1,,35 mpdata,kxx,1,,14 mpdata,kxx,1,,14.2 mpdata,c,1,,460 mpdata,c,1,,480 mpdata,c,1,,530 mpdata,c,1,,675 mpdata,c,1,,670 mpdata,c,1,,660 mpdata,c,1,,780 mpdata,c,1,,820 mp,dens,1,7800 mp,alpx,1,1.78e-5 mptemp,,,,,,,, mptemp,1,25 mptemp,2,100 mptemp,3,200 mptemp,4,300 mptemp,5,400 mptemp,6,500 mptemp,7,600 mpdata,kxx,2,,176 mpdata,kxx,2,,180 mpdata,kxx,2,,184 mpdata,kxx,2,,188 mpdata,kxx,2,,192 mpdata,kxx,2,,198 mpdata,kxx,2,,200 mpdata,c,2,,728 mpdata,c,2,,795 mpdata,c,2,,879 mpdata,c,2,,963 mpdata,c,2,,1089 mpdata,c,2,,1290 mpdata,c,2,,1560 mp,dens,2,2700 mp,alpx,2,9.36e-6 |
