==Introduction==
Review the transfer between the HPC and the FV domains. Review the TUFLOW FV nodestring and mesh check files.
Line 10 ⟶ 9:
<li> The _hpc_transfer_R is the cells where the HPC transfers into the FV model mesh. <br>

Review the TUFLOW FV model mesh:
Line 29 ⟶ 27:
* '''BRough''': The bed roughness (Manning's n) value of the cell.<br>
'''Note:''' Refer to the <u>[https://fvwiki.tuflow.com/Check_Files_mesh_check_R TUFLOW FV Wiki - mesh_check_R]</u> for more details.
<li>The _receiving_mesh_check_R is generally used to check the elevations of the mesh match the model bathymetry (the DEM). Use the 'Identify Features' tool to review the 'ZB' values: <br>

<li> The _receiving_ns_check_L is the nodestrings defined by the 2d_ns layers. Zoom in to the downstream culvert. Observe that the nodestrings have snapped along the closest mesh lines.<br>
'''Note:''' Refer to the <u>[https://fvwiki.tuflow.com/Check_Files_ns_check_L TUFLOW FV Wiki - ns_check_L]</u> for more details.<br>

<li>Zoom in to the upstream boundary. The _catchment_hydraulic_nodestrings is the TUFLOW HPC cell(s) selected by the catchment boundary nodestring. This boundary differs from the non-catchment boundary ('''2d_ns_TC03_DS_boundary_001_L''') in that momentum is transferred from TUFLOW HPC to TUFLOW FV. As such, these are well suited to head of estuary or other tributary inflows.▼
==Review TUFLOW CATCH Check Files==
Review the catchment boundary:
<ol>
<li> In Windows File Explorer, navigate to the '''TUFLOWCATCH\check''' folder and drag and drop '''TC03_001_catchment_hydraulic_nodestrings_R.shp''' into QGIS.
