DefGeom_Quad

Purpose

determines local coordinates and corotational triad of quadrilateral element

Synopsis

[xl,T] = DefGeom_Quad (xyz)

Description

DEFGEOM_QUAD determines local coordinates and corotational triad of quadrilateral element
  [XL,T] = DEFGEOM_QUAD (XYZ);
  the function determines the local coordinates XL and the corotational triad T
  of a quadrilateral element in the configuration with end node coordinates XYZ
  (column 1 for node i, column 2 for node j);
  the corotational triad is given by matrix T whose columns correspond to axes x,y,z resp.
