=Checking the Link=
As with all aspects of modelling, checking your files are being applied as intended is important. The check file to use in the case of 1D 2D linking is of course the 1d_2d_check. The image below you can see the channel being modelled, the Flood Modeller nodes connected via a CN/HX link discussed earlier. The 1d_2d_check file is shown by the blue grid cells. This shows the user the cells being picked up by the HX link lines, it also houses a wealth of information such as the primary Flood Modeller node it links to and if any flags where used in the HX lines for example. Below we are showing the elevation picked up at each link cell, this can be extremely useful in finding any abnormally low cells that have perhaps been incorrectly picked up and are subsequently leading to out of bank flow which in reality wouldn't be there.

=Summary=
Flood Modeller and TUFLOW models can be dynamically coupled to enable a bi-directional connection between the two software using either HX or SX links. The linkage take place when an Flood Modeller node is snapped to a HX or SX boundary, this can be via a CN connection link. The dynamic coupling allows full integration between Flood Modeller networks and full floodplain modelling in TUFLOW 2D to capture complex overland flows.
