Mesh.face_flatness

Mesh.face_flatness(fkey, maxdev=0.02)[source]

Compute the flatness of the mesh face.

Parameters

  • fkey (int) – The identifier of the face.

  • maxdev (float, optional) – A maximum value for the allowed deviation from flatness.

Returns

float – The flatness.

Notes

Flatness is computed as the ratio of the distance between the diagonals of the face to the average edge length. A practical limit on this value realted to manufacturing is 0.02 (2%).

Warning

This method only makes sense for quadrilateral faces.
