DefGeom_2dFrm

Purpose

determines current length and corotational diad of 2-node, 2d frame element

Synopsis

[L,T] = DefGeom_2dFrm (xyz)

Description

DEFGEOM_2dFRM determines current length and corotational diad of 2-node, 2d frame element
  [L,T] = DEFGEOM_2dFRM (XYZ);
  the function determines the length L and the corotational diad T
  of a 2d frame element in the current configuration
  from the end node coordinates XYZ (column 1 for node i, column 2 for node j);
  the corotational diad is given in matrix T whose columns correspond to axes x and y, resp.
