1D Bridges: Difference between revisions

Note: For TUFLOW Builds prior to 2020-10-AA, if the BB bridge is linked directly to a 2D domain (typically via a SX link), there is no adjustment of entrance / exit losses on the sides connected to 2D (adjustment of losses according to approach/departure velocities is the default from 1D channel to 1D bridge to 1D channel). This capability was introduced for 2D channel to 1D bridge to 2D channel, so losses can be automatically adjusted based on the approach/departure 2D velocities across the SX connections by setting "<font color="blue"><tt>Structure Losses SX</tt></font> <font color="red"><tt>==</tt></font><tt> ADJUST</tt>" in Build 2020-10-AA onwards. In the case of 2D connections, refer to the links from the TUFLOW Library below for a discussion on the intricacies and challenges of taking into account contraction and expansion losses for 1D structures connected directly to 2D domains. For B bridges the default is not to adjust losses (please refer to the <u>[https://downloads.tuflow.com/_archive/TUFLOW/Releases/2018-03/TUFLOW%20Manual.2018-03.pdf 2018 TUFLOW Manual]</u> for more information).
