Meshing volume

Eduardo

Hi,

I´m trying to mesh a volume in Gambit but i keep getting this message of error:

"Error: Assertion failed in RefVolume.cc, line 6059: found_1 && found_2 while meshing v_volume.1."

My geometry consists of faces that delimit a car model and faces that create a cube around it. The car is glued to one side of the cube, so if you look from outside you can see the mold of the car.

The volume was created by the car and cube faces. I meshed the car faces, but when I try to mesh the volume the error comes.

Does anyone have an idea of what this means or how can I correct this error?
