Failed mesh due to intersections outside of volume

HI,

Pretty much the title,

The meshing keeps failing due to an intersection:

“The meshing failed due to a self intersection in the mesh on the following entities: edge 1029@Flow region, face 1597@Flow region (-1.556e-2, -1.969e-2, 5.111e-2). Learn more.”

This area is outside of the flow volume. I am a beginner so please go easy!

Perhaps, the following documentation will help resolve the issue:

Also, perhaps keep in mind to import your model in a different file format other than STL. STL files are not recommended (unless for LBM or PWC simulations). STL files contain only faceted data. They are not generally used for simulation purposes and may require more geometry clean up.
