Issues with cell zone

Do you know why I get this error:

One or more cell zones are adjacent to a flow region cavity. Cell zones faces must be inside the flow region.

Hi this is Fillia :slight_smile:
The issue here seems to be that the faces you chose as passive scalar source are placed outside of the flow region’s boundary, instead of being completely inside, does this make sense? If you hide all these solids, these cubes will not disappear, meaning that the flow region does not include the hidden bodies.

Hi Fillis

Thank you it worked :smiley:

Best regards
