Are all Gauss points (integration points) also Barlow points (optimal locations to extract stresses during post-processing stage)? I am guessing no. Only for some very specific elements this might be true. If not, do any commercial FEM codes use Barlow points instead of Gauss points to extract stresses?

  • All the packages I knew (NASTRAN, MARC) used integration points to evaluate all element quantities (temperature, stress, strain). I never encountered one that used Barlow points. I stopped doing FEA for a living in 1995. I don't know what the current state of the art is. No experience with ANSYS. – duffymo Jun 21 '16 at 20:10
  • NAFEMS link: https://www.nafems.org/terms/BARLOW-POINTS/. Looks like Gaussian points are best for primitives like triangles and tetrahedra; reduced points are better for quads and bricks. – duffymo Jun 22 '16 at 14:36
