Deflection ID hypothesis can be applied for meshing curvilinear edges composing your geometrical object. It uses only one parameter: the value of deflection.
A geometrical edge is divided into equal segments. The maximum distance between a point on the edge within a segment and the line connecting the ends of the segment should not exceed the specified value of deflection . Then mesh nodes are constructed at end segment locations and 1D mesh elements are constructed on segments.
To define the Deflection ID hypothesis:
Select this hypothesis in the Create Hypotheses dialog box and click Create. The following dialog box will appear:
