用ANSYS建立了一個簡支梁模型，做完模態分析已經有solution is done了，但是緊接著就出現錯誤：

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.

然后軟件就自己退出了。而且我如果不做模態分析單做瞬態分析或靜力分析都能算，就模態分析不行，有人知道問題出現在哪嗎~急
