用ICEM CFD 给几何体划分六面体网格后，导入到CFX中后求解时报错

CFX提示报错内容如下：ERROR #002100012 has occurred in subroutine cVolSec. Message: A negative ELEMENT volume has been detected. This is a fatal error and execution will be terminated. The location of the first negative volume is reported below. Volume : -0.1958E-06 Location : ( -0.53689E+00, 0.45101E+01, 0.35413E+01)好像是说第一个网格是负体积，不知道是为什么啊？
