Boundary/Constraint to fix node set (all DOF = 0)
(I am working within LS-prepost v4.7)
I am attempting to fix a set of nodes on the bottom side of a cube such that all DOFs are equal to zero. I have tried CONSTRAINED_NODE_SET and a couple other keywords under BOUNDARY and CONSTRAINED, but run into the issue of not being able to select all DOFs = 0. Instead, I still need to define at least one translational or rotational free DOF.
Since I am very new to LS-Dyna in general, I assume this issue is only due to my inexperience and it would be great if someone could point me in the right direction in order to completely fix a given node set (or segment set or face). I have tried searching this question elsewhere and looked through some manuals, but have yet to find an answer.
I have attached a screenshot of the geometry of my model below - the blue plate will be impacting the red cube at a given initial velocity and I am trying to properly constrain the sides of the cube with certain of DOFs equal to zero (e.g. the bottom side having all DOFs = 0).
Thanks in advance for any help.
