DefGeom_Tri

Purpose

determines local coordinates and corotational triad of triangular element

Synopsis

[xl,T]= DefGeom_Tri (xyz)

Description

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