      Hi all, in LS DYNA 3D peridynamics, how is the horizon size calculated? I saw in 2D, the characteristic length is the diagonal of the 2D element, but in 3D how can the horizon size be determined/calculated?

      The characteristic length is the maximum length of the diagonals of the 3D element.

      Thanks a lot, I would also like to ask about the bond-stretch, how is it calculated in 3D elements?
