I am trying to use the overtopping function for several bridges with pressure flow BCs. 4 or 5 of the 12 bridges work fine, however, several return errors at the start of the SRH2D simulation. Attached are screenshots of the two errors I've run into. Interestingly, the model will run fine if the bridges that return errors with overtopping enabled are switch to pressure flow BC with no overtopping. Has anyone run into similar issues/found and ways to resolve? Thanks!
