====== KJ Command ======

KJ,<e1>,[<e2>],[<inc>],<k1>,<k2>,...,<k6>

defines the end release code for the BEAMS J node for the element set defined by <e1>, <e2> (default: <e1>), and <inc> (default: 1) from the active group. The active group must be of type BEAMS. The six values <k1> ... <k6> correspond to the force components P1, P2, P3, M1, M2, M3 at the J node and may take the values 1 and 0 only. If one of the element end forces is known to be zero (hinge or roller), the corresponding digit should be set to 1.
