<li>Open '''TUFLOW\check\TS01_5m_001_Check.gpkg'''. When prompted, open layers '''TS01_5m_001_grd_check_R''' and '''TS01_5m_001_1d_to_2d_check_R'''
<li>Use the 'Apply TUFLOW Styles to Open Layers'.
<li>The '''grd_checkgrd_check_R''' is the 2D grid defined by the 2d_code layer and contains a region object for each cell. ItThis is a useful check file to understand how the model is orientated, and the 2D cell size in relation to the 2D hydraulic featurescontrols and where1D certain calculations occurhydraulic in the modelstructures. In this tutorial, the grid is orientated to align with the downstream road.
<li>The '''1d_to_2d_check_R''' file shows the cells selected by the SX boundary links (thatthese connect the 1D SWMM objects to 2D TUFLOW). It is recommended thatathat the 2D cell width (i.e. cell side legthlength x number of cellcells) be equal or greater than the width of the 1D culvert. Zoom to each structure to inspect the SX links. In all cases the 2D linkage is 10m wide. Is this equal or more than the width of the associated 1D culvert:?
