Purpose

shape functions for 8 node solid (brick) element

Synopsis

[N,dNdx,J] = shape3d (nat,xyz)

Description

SHAPE3D shape functions for 8 node solid (brick) element
  [N,dNdx,J] = SHAPE3D (NAT,XYZ) shape functions for 8 node solid (brick) element

  Input Parameters
  ----------------
  nat  = [ xi eta zeta ] natural coordinates in element
  xyz  = nodal coordinates for element (row i for node i)
  ----------------
  Return Variables
  ----------------
  N    = shape functions in natural coordinates
  dNdx = dNdx(i,j) = derivative of shape function j with respect to geometric coordinate x_i
