In the tables displaying the internal forces of members I can see some x-locations occurring twice with the description "Left" and "Right". What does it mean?
There are discontinuities available on these locations, for example as a result of a concentrated load. The node descriptions "Left" and "Right" indicate the internal forces on the cut sides.
