Hello,

I have designed a 2D naca airfoil and it's control volume. When i try to mesh gambit gives me the following warning:

Warn: mesh size on face v_face.5 is smaller than the geometric tolerance.For an accurate mess use larger mesh sizes and/or create geometry at a larger scale.


What can i do to balance the mesh tolerance with my geometry?

thanks in advance

Can u post the picture of ur 3D model / mesh?

I think u can use Boolean to cut out the portion and use finer mesh on the face it said.

I think you can improve this by redrawing the geometry on a larger scale.

By default tolerance of Gambit is 1e-6. (You can confirm)

If you are drawing the geometry in meters, try millimeters.

Hope this helps.
