ansys中瞬态分析闪退问题？ 20

ansys瞬态分析计算完成后显示solution is done并且好好的，当进入后处理时就闪退了。

查看了error文件里面

 A reference force value times the tolerance is used by the              

 Newton-Raphson method for checking convergence.  The calculated         

 reference FORCE CONVERGENCE VALUE = 0 is less than a threshold.  This   

 threshold defaults to 1.0-2 or is specified as MINREF on the CNVTOL     

 command.  Check results carefully.

 An unexpected error ( SIG$SEGV ) has occurred...  ANSYS internal data   

 has been corrupted.  ANSYS is unable to recover and will terminate.     

 Previously saved files are unaffected.  Please send the data leading    

 to this operation to your technical support provider, as this will      

 allow ANSYS, Inc to improve the program.                                

只有最后一个error就是在进入/post26后出现的，其余都是warning。为什么计算收敛完成了还会出现这种情况呢？
