How to shift the entire cylinder?

      Hi all.

      I consider 1/4 test part in LS-Dyna ACT Workbench.

      The model is a cylinder and it stands on a plane.

      The calculation involves two loads: first, a force presses on the cylinder from above, then the cylinder shifts.

      The problem is that if I apply a shift to the cylinder, due to symmetry it is placed on all 4 sides. And the result is compression, but the complete part does not fit in. 

      How to shift the entire cylinder?

      You can only use symmetry when both the geometry AND the loads are symmetric.  In this case, the load is only symmetric about one plane but not the other.  Use 1/2 symmetry instead of 1/4 symmetry for this analysis.

        Thanks for your answer sir! Tell me, does this answer only apply to Ls-Daina AST? Or is this also for other modules (static, transient, etc.)?

      It applies to all types of analyses.
