TUFLOW 1D2D Boundary Configuration Guidance: Difference between revisions

 

Consider the 1D-2D linking shown in Figure 1.5 The HX boundary “HXb1” shown in red is connected at each end to the same 1D node, whereas the remaining HX boundaries shown in purple are connected at each end to different 1D nodes. In the case that the flow is leaving the 2D domain to enter the 1D channel, the boundary is usually stable without energy correction, however for the reverse case, under high flow velocity conditions, the boundary may display instability or recirculation. If this does occur the problem may be remedied via an energy correction, using the command
