错误1，The calculated reference HT FLOW CONVERGENCE VALUE= 0 is less than the  
default minimum of 1E-6 (which can be modified using the MINREF field   
of the CNVTOL command).  Check results carefully.
做的是加温度的谐响应分析，这个错误应该导致了最后温度只有第一步存在，谐响应的后几步温度全是0了。
2，No stress stiffness matrix for element 3142 found on the EMAT file.     
  Probably due to missing EMATWRITE,YES in the first load step.
关键是加了 EMATWRITE,YES 也还是出现这样的错误！
各位大虾们，请问以上的错误怎么解决呢~~
