Reply To: How to apply displacement derivative dependent force on bunch of nodes in apdl?

[dlooman]

UZ() is what we call a "get function."  It gets the current value of the displacement at a node, in this case node 11.   But it's a mistake in my input.  It should be v_11 = delta_uz_11/0.01  , the change in uz at node 11 divided by the time step.
