      Do I use the PBM method to calculate 1/4 model? When I try to build a 1/4 model, the particles appear on the other side of the domain like this.

      This is my keyword:

      Hello,

      So, you built a quarter symmetry model and the particles go outside the domain? Do the particles go across a symmetry plane? Or do the particles escape at another location? Could you show the problem in more details with screenshots?

      If you were to build a full model, would you expect particles to cross this boundary or no?

      Which LS-DYNA solver are you using?

       

      Reno.
