VABS Recovery stress (nodes/Gaussian points)

  1. Raphael Nardin

    Hi !

    I am using the recovery functionnality of VABS, and I was wondering what is the best option between getting stresses at nodes or at Gaussian points. I guess it is equivalent if the mesh is fine enough, however are stresses at nodes extrapolated or averaged from the surrounding Gaussian points ?

    Regards,

      Gaussian stress values should be the most accurate. Nodal values are extrapolated from Gaussian values. ---- Emailed forum response from wenbinyu@purdue.edu
