Introduction

Review the transfer between the HPC and the FV domains. Review the TUFLOW FV nodestring and mesh check files.

Review HPC Transfer Check Files

Review the transfer from the HPC model domain into the FV model domain:

  1. In Windows File Explorer, navigate to the TUFLOWCATCH\check folder and drag and drop TC03_001_catchment_hydraulic_hpc_transfer_R.shp and TC03_001_catchment_hydraulic_grd_check_R.shp into QGIS.
  2. The _hpc_transfer_R is the cells where the HPC transfers into the FV model mesh.


Review TUFLOW FV Check Files

Open the following check files from the TUFLOWCATCH\check folder into QGIS:

  • TC03_001_receiving_mesh_check_R.shp
  • TC03_001_catchment_hydraulic_nodestrings_R.shp
  • TC03_001_receiving_ns_check_L.shp

Review the TUFLOW FV model mesh:

  1. Click on the 'Apply TUFLOW Styles to Open Layers' symbol from the TUFLOW Plugin toolbar.
  2. The _receiving_mesh_check_R is the TUFLOW FV model domain defined by the Stream_Mesh.2dm. For each cell, it contains:
    • IDX2 and IDX3: The cell 2D and 3D ID number. As this is an only 2D model, the IDX3 is set to the IDX2 attribute.
    • CTRDX and CTRDY: The X and Y coordinates of the cell center.
    • Mat: The material ID applied in the cell.
    • ZB: The elevation of the cell center.
    • BRough: The bed roughness (Manning's n) value of the cell.
  3. The _receiving_mesh_check_R is generally used to check the elevations of the mesh match the model bathymetry (the DEM). Review the 'ZB' values:


Review the boundary and culvert nodestrings:

  1. Zoom in to the downstream culvert. Observe that the nodestrings have snapped along the closest mesh lines.


  2. Zoom in to the upstream boundary. The_catchment_hydraulic_nodestrings is the TUFLOW HPC cell(s) selected by the catchment boundary nodestring. more info?
