Hi all,
i am doing a simulation where two rectangular blades are inserted into a rectangle. these blades are inserted in such a way that no fluid can pass. so one vertex of each blade is coincident on each other. and diagonally opposite vertex is coincident with sides of rectangle. so when i am generating a surface it is giving a warning saying no close sketch.
i am attaching my geometry here so that you guys can look into it.
any kind of help will be appreciated. Thanks in advance

this is link for my geometry.
