Name

Remove Short Sides (RemoveShortSide) — Eliminate the shortest side of a quadrilateral.

Synopsis

RemoveShortSide(ratio)

Details

  • Base class: Rationalizer
  • Parameters:

    ratio
    Maximum acceptable ratio of the lengths of the second shortest and the shortest sides. Type: A real number.

Description

RemoveShortSide is a Rationalizer applied by the Rationalize Skeleton modifier. It removes the shortest segment or segments of a quadrilateral Element. When used as part of a SpecificRationalization, RemoveShortSide is applied to Elements in two categories:

  • The quadrilateral has one short side, as shown in lines (a) and (b) in Figure 6.102. The rationalizer is used if the ratio of the lengths of the two shortest sides is greater than the given ratio. The target element is converted into a triangle, and a neighboring Element is either converted into a triangle or deleted, depending on its shape.

  • The quadrilateral has two short sides opposite one another, as shown in line (c) of Figure 6.102. The rationalizer is applied if the ratio of the length of the shorter long edge to the length of the longer short edge is greater than ratio. The target Element is deleted and the neighboring Elements are either turned into triangles or deleted.

Applying RemoveShortSide

(a) The highlighted quadrilateral Element has one short side neighboring a triangle. The short side is removed, turning the Element into a triangle and deleting the neighbor.

(b) The neighbor is a quadrilateral and is turned into a triangle.

(c) The highlighted Element is a quadrilateral with two opposing short sides. The Element is removed, along with the neighboring triangle on the right. The quadrilateral on the left becomes a triangle.
