Problem in volume meshing
 

Hi,

I am modelling a car cabin using StarCCM+. Wrapping and surface meshing has been successfully completed but I am facing problem in volume meshing.
I am getting following error:
SERIAL_FATAL:Subsurfacer:: CheckTrueIntersection: Original surface is self intersecting.

I have checked remeshed surface but there are zero self intersecting surfaces. Can any one please tell me the possible reason of error?
