      Hi all.
      Faced the problem of fixing the SPH body with a solid body in the Ansis Workbench Ls-Dyna ACT.
      It looks like this is an Ansis bug?
      It is not possible to attach SPH bodies and rigid bodies to each other.
      The LS-Dyna single module prepost has a TIED_NODES_TO_SURFACES pin that allows you to pin the rigid body segment and SPH of the body.
      But ANSYS WB LS-DYNA ACT does not have this option.
      Tell me, maybe it appeared in the 2022 version? Or is there another way?
      I also tried using snippet but it didn't work. When exposed to the SPH body, it begins to slide over the solid body.
      How to solve this problem in ANSYS WB LS-DYNA ACT?
      There was only one such question, and it is not resolved: https://forum-legacy.ansys.com/discussion/34599/fix-sph#latest
