      Hello, I am conducting a two-dimensional SPH particle simulation of rock triaxial compression. I am unsure how to apply confining pressure to the boundary particles. I haven't been able to find the relevant keywords.

      Hi, 

      An idea to try would be to use a shell body tied to the SPH nodes through a tied contact definition( contact_2d_node_to_solid_tied), and then apply traction to the shell body to generate pressure within the SPH domain.

      Cheers, Ram
