Dear colleagues,
I’m currently performing a 1D steady simulation of a natural river with one bridge. In the detailed output tables, for the bridge, there is this warning: “For the final momentum answer at the bridge, the upstream energy was computed lower than the downstream energy. This is not physically possible, the momentum answer has been disregarded.”
What does this means? Do I have to change something in the bridge modelling approach?
Thanks in advance.
Miguel
