negative element volume (CFX-10.0)

Hi,

I get the following error message during the initialization of a frozen rotor computation:

+--------------------------------------------------------------------+ | ERROR #002100011 has occurred in subroutine cVolSec. | | Message: | | A negative sector volume has been detected. Execution will proceed | | but this is a possible cause of robustness problems. | | The location of the first negative volume is reported below. | | Volume : -0.1548E-14 | | Location : ( -0.53471E-01, -0.11722E+01, -0.45800E+02) | | This warning may be made fatal by setting the expert parameter | | 'negative volume option = 1'. | +--------------------------------------------------------------------+

I have checked in ICEM, and I am pretty sure there is no negative elements in the mesh. So I am wondering what could be wrong. Has anyone experienced the same? I am thinking that the error might origin from the import in CFX-Pre, but I am not sure.
