Error when defining enclosure

Hi, I’m trying to do a CFD simulation for my vertical wind turbine design project and this is the first time I’m attempting to run this type of simulation.
I’m having a problem in defining the enclosure for my assembly. When I want to assign the seed face, it said:

The geometry could not be combined at face27@9418 bracket:4. Please consider cleanup operations in your CAD tool.

Some help on this matter is really appreciated. Thanks.

From inspecting the CAD on Onshape, there seem to be a number of interfering parts, which can cause an enclosure operation to fail (see common causes here):

Make sure to merge these volumes in a CAD tool (and double check for gaps/overlapping parts), and you should be fine!
