ANSYS热分析加载荷出错，请问到底是什么原因
|
|
各位，我用ANSYS仿真生死单元，建模加初始温度载荷稳态分析的时候老出错，请各位给我看看怎么回事： 错误一：Specified degree of freedom constraint TEMP at unused node 7331. 错误2： Material property DENS of material 1 of element 5 is evaluated at a temperature of 0, which is below the supplied temperature range. Temperature range checking terminates. 错误3：There are no active degrees of freedom. 错误4：A reference heat flow value times the tolerance is used by the Newton-Raphson method for checking convergence. The calculated reference HT FLOW CONVERGENCE VALUE= 2.970385058E-14 is less than a threshold. This threshold defaults to 1.0e-6 or is specified as MINREF on the CNVTOL command. Check results carefully. 能解决几个是几个，谢谢各位大神！！！！！！！ 命令流： /prep7 et,1,plane77 et,2,solid70 mptemp,1,25,90,160 mpdata,dens,1,1,8500,8500,8500 mpdata,dens,2,1,1150,1150,1150 mpdata,c,1,1,380,380,380 mpdata,c,2,1,1470,1470,1470 mpdata,kxx,1,1,130,130,130 mpdata,kxx,2,1,0.03,0.03,0.03 rect,0,0.1,0,0.1 asel,s,area,,1 aatt,1 esize,0.004 mshkey,1 mshape,0 amesh,1 extopt,esize,5 extopt,aclear,1 extopt,attr,1,1,1 mat,1 vext,1,,,,,-0.02 rect,0.03,0.07,0.03,0.07 asel,s,area,,7 aatt,2 esize,0.004 mshkey,1 mshape,0 amesh,7 mat,2 vext,7,,,,,0.02 allsel finish /prep7 et,1,plane77 et,2,solid70 mptemp,1,25,90,160 mpdata,dens,1,1,8500,8500,8500 mpdata,dens,2,1,1150,1150,1150 mpdata,c,1,1,380,380,380 mpdata,c,2,1,1470,1470,1470 mpdata,kxx,1,1,130,130,130 mpdata,kxx,2,1,0.03,0.03,0.03 rect,0,0.1,0,0.1 asel,s,area,,1 aatt,1 esize,0.004 mshkey,1 mshape,0 amesh,1 extopt,esize,5 extopt,aclear,1 extopt,attr,1,1,1 mat,1 vext,1,,,,,-0.02 rect,0.03,0.07,0.03,0.07 asel,s,area,,7 aatt,2 esize,0.004 mshkey,1 mshape,0 amesh,7 mat,2 vext,7,,,,,0.02 allsel finish |
